We currently have three categories of string parameters: `string`,
`string[]` and `StringBuilder`. (OpenTK 1.2 adds one more: `ref
string`.) Each category needs to be marshaled separately into a native
character array.
This commit implements the following changes:
- string[] epilogues are now correctly emitted, instead of being
ignored.
- string[] prologues and epilogues now use the same local variable name.
- all epilogues are now generated with a single pass over the function
parameters, instead of requiring a separate pass for each category.
- string prologues and epilogues now allocate local variables based on
the relevant parameter *name* rather than the parameter *type*.
Fixes issue #144.
Since GL_TRUE and GL_FALSE match .Net true and false (1 and 0,
respectively), we can simply reinterpret the byte value as a bool.
In the future, we could issue a `(if value == 0 then false else true)`
statement for added safety, but this does not appear to be necessary
right now.
Mono can use ldlen and ldelema on both 1d arrays (vectors) and 2d/3d
arrays. However, .Net can only use these instructions on 1d arrays -
higher rank arrays must use get_Length and Address explicitly.
eglGetProcAddress cannot be used to retrieve
entry points of core functions. Instead, we
use [DllImport] for core functions and function
pointers for extension functions.

[Rewrite] Remove calli prototypes
When a function is called indirectly via a function pointer, its
prototype is not required (the prototype is added as a callsite at the
calli invocation.) Removing these prototypes reduces binary size by
roughly 400KB.

[Rewrite] Call DllImports directly
When a function does not have an allocated slot (i.e. slot = -1), then
we will call its DllImport signature directly.

[Bind] Do not allocate slots for DllImports

[Bind] Added option to use DllImports
This is necessary for the core functionality of OpenGL ES, where
eglGetProcAddress returns null or garbage (the latter on Android.)
Wrap new generated binding calls with using ErrorHelper. Sets up a try
to call the method in and a finally block to call Dispose on the
ErrorHelper. Currently hardcoded to only work for the graphics modules.
Starting with OpenGL 4.2, strings passed to GL.ShaderSource are allowed
to contain multi-byte characters in comments (issue #18). This patch
modifies the marshaling code to use UTF8.GetBytes in order to marshal
strings, instead of Marshal.StringToHGlobalAnsi().
Tools now go to the Binaries/Tools/[Debug|Release] directory. OpenTK
remains at BInaries/OpenTK/[Debug|Release].
Mono.Cecil and IKVM now reside under the Dependencies/managed/
directory.
