Kerberos library for Node.js forked to fix some C++ issues

# Kerberos for Node.js

krb5 is a Node.js native binding for kerberos. It is a node.js implementation of
kerberos client tools, such as :
- kinit (keytab, or password)
- kdestroy
It uses the [MIT Kerberos] native library.
It is also able to generate a SPNEGO token. [SPNEGO] is a GSS mechanism to
authenticate through HTML requests.
Please see the first example in the samples directory for a concrete use case.

## Installation

The installation assumes that you have mit-kerberos installed on your computer. 
On Linux, you shall be all set. On Windows or Mac OS, please read the
corresponding section below. Once mit-kerberos is installed, run

```bash
npm install
```

## Windows

To compile this library in windows, you need a complete visual studio compile
chain, please refer to this [webpage][visual studio]. If you have a 32 bit OS,
please delete binding.gyp and rename \_binding32.gyp before install.

## Mac OS X

If you encounter troubles with your kerberos version, please compile kerberos
using the following instructions.

Your include path must contain:
krb5.h
*   *gssapi.h*
*   *gssapi/gssapi_krb5.h*

Your library path must contain:
*   *krb5* library
*   *gssapi_krb5* library

Here's some instructions on how to install the Kerberos and GSS libraries. You
can download the latest version of the [MIT Kerberos Distribution][MIT Kerberos Dist].
Unless you specify the "--prefix" option to `configure`, the library will be
installed inside "/usr/local".

```bash
wget http://web.mit.edu/kerberos/dist/krb5/1.15/krb5-1.15-beta1.tar.gz 
tar -xzf krb5-1.15-beta1.tar.gz 
cd krb5-1.15-beta1/src
./configure
make
sudo make install
```

If kerberos is not installed in a directory not included in include and/or library path (if you have manually
compiled kerberos in a specific directory for example), please modify the
binding.gyp present in the package root folder with the following properties:

```js
{
  'targets': [{
    'target_name': 'krb5',
    'include_dirs': ['/path/to/kerberos/include/dir/','/path/to/kerberos_gssapi/include/dir/'],
    'libraries': ['/path/to/libkrb5', '/path/to/libgssapi_krb5']
  }]
}
```

# Usage

## API

```coffeescript
k = krb5
  principal
  password: 'mypass' # If keytab not set
  keytab: '/etc/security/keytabs/me.keytab' # If password not set, default keytab if not defined
  service_principal: 'HTTP@domain.com'
  renew: true
k.kinit options, (err) ->
k.kdestroy (err) ->
k.token (err, token) ->
  console.log token
```

## Spnego

```coffeescript
krb5 = require 'krb5'
krb5.spnego
  principal: 'me@MY.REALM'
  password: 'mypass' # If keytab not set
  keytab: '/etc/security/keytabs/me.keytab'  # If password not set, default keytab if not defined
  service_principal: 'HTTP@domain.com'
, (err, token) ->
  console.log token
```
