All sources were moved to external/qemu/distrib/android-emugl
to make it easier to modify both the emulator and host libraries
at the same time. See:

    https://android-review.googlesource.com/#/c/118203/

As such, the sources in this directory are now ignored and can be
safely removed.

When building the host version of the gtest library, always
include -lpthread as part of LOCAL_LDLIBS, otherwise the build
will fail when cross-compiling for Windows on Linux.

Without this fix, the GLESv1 encoder library will link to the
pixelDataSize() function that is defined in the GLESv2 encoder library,
which results in bugs, like the boot animation now showing with -gpu on.

This patch doesn't change the generated decoder libraries, nor does it
affect the encoder ones until external/qemu/distrib/update-emugl-sources.sh
is called. When the latter script will be run, other changes under
device/generic/goldfish/generic/ will be needed to fix the namespace
of the functions being defined in GLEncoderUtils.cpp and GL2EncoderUtils.cpp

This patch modifies a few GLESv1 and GLESv2 function declaration
to use the correct constness for the parameters of a few functions.

This fixes build breaks when the generated encoders are used with
recent Khronos headers.

This patch fixes the parsing of type declarations and parameter
declarations to:

- Properly recognize complicated types like 'const int* const*'
  which previously required omitting spaces (e.g. 'const int*const*')
  to be recognized by the parser.

- Normalize the type strings (e.g. 'const char **items' -> 'const char** items')

- Add a unit test program (emugen_unittests) to check emugen's internal
  functions. For now this only applies to the new functions introduced
  in the new header Parser.h

+ Update emugen test suite accordingly.

For GL_STENCIL_VALUE_MASK and the like, glGetFloatv returns -1
and this is incorrect, according to GLES 2 spec. This commit
does proper casts to get sensible value.

When deleting a program that is still in use, its delete status
should set to true and the actual deletion should happen later
when the program is not in use.
