Renamed function for consistency with a possible Mesh manipulation functions (maybe added in a future). Naming follows Image*() manipulation functions.

It has no sense to be inside LoadOBJ(), mesh processing moved to own functions: MeshTangents() and MeshBinormals(). Not exposed to user yet.

Found by LeakSanitizer in #494.

$ make clean
Makefile:296: *** missing separator.  Stop.

Fixes UB in #489, found by UBSan.

Width specifier doesn't include NUL terminator.
Fixes #487 found by AddressSanitizer.

jar_xm: Workaround for unaligned pointer accesses

jar_xm.h does some shady pointer casts leading to unaligned accesses
and breaking strict aliasing. x86 has special circuitry for doing
unaligned accesses, but on other architectures, it may trap and require
kernel fix-up or crash outright. With this patch, one obstacle in
porting raylib to the GameBoy Advance has been removed. Go for it ;-)

To avoid having to rewrite that `mempool' code, insert padding before
structs and instruct the compiler (GCC, most importantly), to be gentle
when optimizing.

This fixes #490 (Unless we got ourselves 256-bit pointers, if so,
hello future!)

Update Makefiles. Automate example usage of staged libraylib.so.

This reverts commit 6ffc8cb799.
and commit e4d7bbec1e.
which I pushed by mistake...

To make bugs like #485, #486, #487 and #488 easier to find in future.

RAYMATH_EXTERN_INLINE was renamed to RAYMATH_HEADER_ONLY, which user code
may define if they want to use it as header-only library. If multiple
files in the same project define RAYMATH_HEADER_ONLY, they might each
have duplicate out-of-line definitions of the same functions.

By default, raymath.h exposes inline definitions, which instructs the
compiler _not_ to generate out-of-line definitons, if out-of-line
definitions are required, those of the file defined with
RAYLIB_IMPLEMENTATION are used instead. There may be only one such file.

In C++ mode, the compiler will select only one out-of-line definition
automatically, so no need to define a RAYLIB_IMPLEMENTATION.

Unfortunately, we have to remove raymath function declaration from
raylib.h as those declarations would lead to duplicate out-of-line
definitions which would yield linker errors. This problem didn't
exist with GNU89 or C++, because there multiple defintions are ok,
but in C99 they aren't.

Besides making it thread-safe, it suppresses a GCC warning
when making them static inline in an upcoming patch.

Added struct Vector4 for convenience

When UnloadModel() --> UnloadMaterial(), avoid unloading default shader (if used) and avoid unlaoding default texture (if used), that data is managed by raylib internally. The question is... should UnloadModel() also UnloadMaterial()?

Apparently, before macOS Sierra version, clock_gettime was not available, using MATCH timming system instead

Integrate develop branch (LAST INTEGRATION)

Supported UTF8 range equivalent to [128..255] (80h..FFh)
Exposed and renamed text function GetGlyphIndex()
Renamed spriteFont parameter name to simply font
Small security check on transmission mission ending screen

Support string replacing to generate newspaper headline
ISSUE: UTF8 characters not supported when drawing to Image

Add Builder project files

They were named so for compatibility with make, but make doesn't use
the anymore. I always forget whether it's SHARED_RAYLIB or
RAYLIB_SHARED...

For now, RAYLIB_SHARED and STATIC_RAYLIB may still be used,
but print a deprecation warning.

Integrate develop branch

Rename: GetHexValue() renamed to ColorToInt()
Added: ColorToHSV()

Integrate develop branch into master

Linux make install improvements

These changes are intended to provide context and control over the Linux make install process. make install RAYLIB_LIBTYPE=SHARED now works as expected. libraylib.so is properly installed with attendant runtime links. The examples will be running against the newly installed libraylib.so unless otherwise specified with RAYLIB_RUNTIME_PATH. See raylib/src/Makefile and raylib/examples/Makefile for usage of RAYLIB_INSTALL_PATH, RAYLIB_H_INSTALL_PATH, and RAYLIB_RUNTIME_PATH variables. RAYLIB_RUNTIME_PATH in particular is interesting for portability since sudo isn't needed.
The default configuration and workflow is essentially unchanged and unaffected.

If user doesn't build the static library,
`pkg-config --static --libs raylib` should be equivalent to
`pkg-config --libs raylib`.
