This change makes GLConsumer use the EGL_ANDROID_image_crop extension when
available on a device. The crop rectangle is passed to the EGL driver when
creating EGLImages, allowing the crop to be performed by the driver rather than
using the texture transform matrix.

EGL now picks the buffer format out of a small set
of formats compatible with CPU consumers instead of
using the EGL_NATIVE_VISUAL_ID.

If the implementation eglCreateContext failed, we called
eglGetError(), so we could check that it set the EGL error properly.
But since we'd already called this, when the app called eglGetError()
it would get EGL_SUCCESS!

We've had the extended behavior since Android 4.3, but the extension
hadn't been ratified by Khronos yet so we couldn't add it to the
extension string.

this means they only have access to the consumer end of
the interface. we had a lot of code that assumed consumers
where holding a BufferQueue (i.e.: both ends), so most of
this change is untangling in fix that

If there are two or more buffers pending that are ready for
immediate presentation, drop all but the last one.
Any code that didn't explicitly specify timestamps for buffers
was using the default value (auto-generated "now"). As a result,
surfaceflinger would drop frames whenever more than one buffer
was queued. We now use zero as the auto-generated timestamp,
and we don't set the timestamp in eglBeginFrame().

Fallout from the Flattenable change, update all its uses.
Additionnaly, fix/tighten size checks when (un)flatten()ing
things.
Removed the assumption by some flattenables (e.g.: Fence)
that the size passed to them would be exact (it can
and will be larger in some cases)
The code in Parcel is a bit complicated so that we don't
have to expose the full implementation (and also to
keep the code smallish).

this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:
- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
those flags are used to put the BufferQueue in a mode where it
will never block if both flags are set. This is achieved by:
- returning an error from dequeueBuffer() if it would block
- making sure a buffer is always available by replacing
the previous buffer with the new one in queueBuffer()
(note: this is similar to what asynchrnous mode used to be)
Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.

in the common case this saves one instructions per jump
(which will help with the i-cache).
this change also gets rid of the "use slow tls" option,
which was useless. So at least now architectures that don't have
assembly bindings will perform much better.

Also, fixed the "gen" script to update the static/egl/*.java files
as part of doing an update. Altered the "git" lines to change
directories before invoking git -- necessary because we're now
split between frameworks/base and frameworks/native.

destroyed but current-to-a-thread resources are only destroyed
when they're made not-current; however, we were not destroying
those when the thread itself terminated, causing these resources
to be leaked forever.
we now install a tls-key destructor that takes care of this
by calling eglReleaseThread upon thread termination.

The getarray() function checks to see if there's enough room in
the buffer, but it's using a byte count for the available size
and a possibly non-byte count for the space required. Dividing
down by the unit size corrects the problem.

the code intended to filter out the software-renderer, but the
test as written was essentially a no-op.
the problem didn't happen most of the time because we had
updated egl.cfg to not even list the software renderer.
the test as written didn't generate a compile-time error
because String8 has a const char* cast operator; but the
end result was to compare pointers instead of the string
itself.

Some of these are new ES3 functions, some are existing ES2 functions
that can now use the new pixel pack/unpack buffer bindings.
glDrawElementsInstanced needs a special case since the pointer/offset

Return values are declared with the C return type, but the JNI
function returns the JNI return type. In the case of GLsync/jlong as
in glFenceSync(), this causes a compile error. So the generator now
explicitly casts the return value to the JNI return type.

This change adds ES3 functions to GLES30.spec, disabling any that
require non-trivial changes for the generator to handle.
Steps taken to add these:
- Copy ES3 function declarations from gl3.h
- Remove GL_APICALL, GL_APIENTRY, and semicolon from each declaration
- Add whitespace around parens and *s as required by the parser
- Comment out functions that the generator doesn't understand or that
it generates bad Java interfaces for (by inspection).

to ES2 functions are now GLfloat instead of GLclampf. Both are
typedefs for 'float', so this is a source and binary compatible change.

We now detect at runtime which sync features to use, which
allows us to remove a lot of the compile-time configuration
options. There is still one option though, to disable
KHR_fence_sync on some devices (which are more efficient
without it).
- added a backdoor to get the vendor's EGL strings
the new logic is:
- use always ANDROID_native_fence_sync if available
- fallback to KHR_fence_sync if available and not disabled
by the compile-time option
- use KHR_wait_sync if available and either of the above is
enabled

This isn't really right either, but avoids having an extra buffer that
the consumer has to drain which it might not be expecting.
To be correct, disconnecting a surface from a context should retain
the current buffer and continue using it when reconnected. The buffer
should only be canceled when the surface is destroyed. That will wait
for a later change.

- added support for comments in checks.spec
- added most missing checks
- added and commented with // special-cased functions
- added and commented with # functions that are still missing validation checks
- moved glGet* to a special case and updated all the "pnames" from the khronos spec
- changed ifcheck to default to 1 value. this allows us to simplify the checks.spec file
and handle unknown pnames automatically (they'll be validated against 1 value, if
it happens to need more, the call will go through but the validation will not
happen).
- refactored the cpp headers in to a common header + GLES version specific
header
