  // Big Integer Library v. 5.5
  // Created 2000, last modified 2013
  // Leemon Baird
  // www.leemon.com
  //
  // Version history:
  // v 5.5  17 Mar 2013
  //   - two lines of a form like "if (x<0) x+=n" had the "if" changed to "while" to
  //     handle the case when x<-n. (Thanks to James Ansell for finding that bug)
  // v 5.4  3 Oct 2009
  //   - added "var i" to greaterShift() so i is not global. (Thanks to Péter Szabó for finding that bug)
  //
  // v 5.3  21 Sep 2009
  //   - added randProbPrime(k) for probable primes
  //   - unrolled loop in mont_ (slightly faster)
  //   - millerRabin now takes a bigInt parameter rather than an int
  //
  // v 5.2  15 Sep 2009
  //   - fixed capitalization in call to int2bigInt in randBigInt
  //     (thanks to Emili Evripidou, Reinhold Behringer, and Samuel Macaleese for finding that bug)
  //
  // v 5.1  8 Oct 2007 
  //   - renamed inverseModInt_ to inverseModInt since it doesn't change its parameters
  //   - added functions GCD and randBigInt, which call GCD_ and randBigInt_
  //   - fixed a bug found by Rob Visser (see comment with his name below)
  //   - improved comments
  //
  // This file is public domain.   You can use it for any purpose without restriction.
  // I do not guarantee that it is correct, so use it at your own risk.  If you use 
  // it for something interesting, I'd appreciate hearing about it.  If you find 
  // any bugs or make any improvements, I'd appreciate hearing about those too.
  // It would also be nice if my name and URL were left in the comments.  But none 
  // of that is required.
  //
  // This code defines a bigInt library for arbitrary-precision integers.
  // A bigInt is an array of integers storing the value in chunks of bpe bits, 
  // little endian (buff[0] is the least significant word).
  // Negative bigInts are stored two's complement.  Almost all the functions treat
  // bigInts as nonnegative.  The few that view them as two's complement say so
  // in their comments.  Some functions assume their parameters have at least one 
  // leading zero element. Functions with an underscore at the end of the name put
  // their answer into one of the arrays passed in, and have unpredictable behavior 
  // in case of overflow, so the caller must make sure the arrays are big enough to 
  // hold the answer.  But the average user should never have to call any of the 
  // underscored functions.  Each important underscored function has a wrapper function 
  // of the same name without the underscore that takes care of the details for you.  
  // For each underscored function where a parameter is modified, that same variable 
  // must not be used as another argument too.  So, you cannot square x by doing 
  // multMod_(x,x,n).  You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
  // Or simply use the multMod(x,x,n) function without the underscore, where
  // such issues never arise, because non-underscored functions never change
  // their parameters; they always allocate new memory for the answer that is returned.
  //
  // These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
  // For most functions, if it needs a BigInt as a local variable it will actually use
  // a global, and will only allocate to it only when it's not the right size.  This ensures
  // that when a function is called repeatedly with same-sized parameters, it only allocates
  // memory on the first call.
  //
  // Note that for cryptographic purposes, the calls to Math.random() must 
  // be replaced with calls to a better pseudorandom number generator.
  //
  // In the following, "bigInt" means a bigInt with at least one leading zero element,
  // and "integer" means a nonnegative integer less than radix.  In some cases, integer 
  // can be negative.  Negative bigInts are 2s complement.
  // 
  // The following functions do not modify their inputs.
  // Those returning a bigInt, string, or Array will dynamically allocate memory for that value.
  // Those returning a boolean will return the integer 0 (false) or 1 (true).
  // Those returning boolean or int will not allocate memory except possibly on the first 
  // time they're called with a given parameter size.
  //

  // bigInt  addInt(x,n)            //return (x+n) where x is a bigInt and n is an integer.
  // string  bigInt2str(x,base)     //return a string form of bigInt x in a given base, with 2 <= base <= 95

  // Profiling shows:
  //     randTruePrime_() spends:
  //         10% of its time in calls to powMod_()
  //         85% of its time in calls to millerRabin()
  //     millerRabin() spends:
  //         99% of its time in calls to powMod_()   (always with a base of 2)
  //     powMod_() spends:
  //         94% of its time in calls to mont_()  (almost always with x==y)
  //
  // This suggests there are several ways to speed up this library slightly:
  //     - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
  //         -- this should especially focus on being fast when raising 2 to a power mod n
  //     - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
  //     - tune the parameters in randTruePrime_(), including c, m, and recLimit
  //     - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
  //       within the loop when all the parameters are the same length.
  //
  // There are several ideas that look like they wouldn't help much at all:
  //     - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
  //     - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
  //     - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
  //       followed by a Montgomery reduction.  The intermediate answer will be twice as long as x, so that
  //       method would be slower.  This is unfortunate because the code currently spends almost all of its time
  //       doing mont_(x,x,...), both for randTruePrime_() and powMod_().  A faster method for Montgomery squaring
  //       would have a large impact on the speed of randTruePrime_() and powMod_().  HAC has a couple of poorly-worded
  //       sentences that seem to imply it's faster to do a non-modular square followed by a single
  //       Montgomery reduction, but that's obviously wrong.

-----------
A gettext compatible i18n library for modern JavaScript Applications

by Alex Sexton - AlexSexton [at] gmail - @SlexAxton
WTFPL license for use
Dojo CLA for contributions

Jed offers the entire applicable GNU gettext spec'd set of
functions, but also offers some nicer wrappers around them.
The api for gettext was written for a language with no function
overloading, so Jed allows a little more of that.

Many thanks to Joshua I. Miller - unrtst@cpan.org - who wrote
gettext.js back in 2008. I was able to vet a lot of my ideas
against his. I also made sure Jed passed against his tests
in order to offer easy upgrades -- jsgettext.berlios.de

 *
 *  This extension already exists in some browsers (namely, Firefox 3), but

 *
 *  Parameters:
 *    (Object) obj - The object that will become 'this' in the bound function.

 *

 *  complete.
 *
 *  The user will also have several event handlers defined by using
 *  addHandler() and addTimedHandler().  These will allow the user code to
 *  respond to interesting stanzas or do something periodically with the
 *  connection.  These handlers will be active once authentication is
 *  finished.
 *
 *  To send data to the connection, use send().
 */

/** Constructor: Strophe.Connection
 *  Create and initialize a Strophe.Connection object.
 *
 *  The transport-protocol for this connection will be chosen automatically
 *  based on the given service parameter. URLs starting with "ws://" or
 *  "wss://" will use WebSockets, URLs starting with "http://", "https://"
 *  or without a protocol will use BOSH.
 *
 *  To make Strophe connect to the current host you can leave out the protocol
 *  and host part and just pass the path, e.g.
 *
 *  > var conn = new Strophe.Connection("/http-bind/");
 *
 *  WebSocket options:
 *
 *  If you want to connect to the current host with a WebSocket connection you
 *  can tell Strophe to use WebSockets through a "protocol" attribute in the
 *  optional options parameter. Valid values are "ws" for WebSocket and "wss"
 *  for Secure WebSocket.
 *  So to connect to "wss://CURRENT_HOSTNAME/xmpp-websocket" you would call
 *
 *  > var conn = new Strophe.Connection("/xmpp-websocket/", {protocol: "wss"});
 *
 *  Note that relative URLs _NOT_ starting with a "/" will also include the path
 *  of the current site.
 *
 *  Also because downgrading security is not permitted by browsers, when using
 *  relative URLs both BOSH and WebSocket connections will use their secure
 *  variants if the current connection to the site is also secure (https).
 *
 *  BOSH options:
 *
 *  by adding "sync" to the options, you can control if requests will
 *  be made synchronously or not. The default behaviour is asynchronous.
 *  If you want to make requests synchronous, make "sync" evaluate to true:
 *  > var conn = new Strophe.Connection("/http-bind/", {sync: true});
 *  You can also toggle this on an already established connection:
 *  > conn.options.sync = true;
 *
 *
 *  Parameters:
 *    (String) service - The BOSH or WebSocket service URL.
 *    (Object) options - A hash of configuration options
 *
 *  Returns:
 *    A new Strophe.Connection object.
