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.

The decoders generated by emugen pass addresses that come directly
from the stream to EGL/GL functions. Sometimes, these addresses are
not properly padded with regards to the type of data being transfered
and this can crash some implementations (e.g. OSMesa being compiled
with -msse by default, and doesn't build without it).
This patch introduces two helper classes in ProtocolUtils.h, named
InputBuffer and OutputBuffer, which are used to auto-align buffer
pointers, then make the generated decoder code use them.

The decoder didn't properly handle GLsizeiptr and GLintptr values, which
are always 32-bit on the wire, but can be 64-bit on the host. I.e. it
did something like that to read them from the stream:
*(GLsizeiptr*)(ptr + offset)
This fixes the issue by using templates to generate host-type-specific
functions that properly read data from the stream and convert it to the
appropriate host type.

This patch cleans up the build files for the GPU emulation libraries
(i.e. there is no need to test for BUILD_EMULATOR_64BITS anymore,
filtering is now handled by the build system directly).
+ Remove a bunch obsolete tests, which were not unit tests, despite
their name beginning with ut_xxxx.
Which includes removing dependency on SDL too.
+ Remove -m64 and -fPIC flags from compilation. These are not
necessary anymore (again, the build system now takes charge of
placing them when necessary), and generated link-time warning
when building Windows executables.
+ Remove a few declarations related to the now-obsolete platform
build (these libraries are only built with the emulator's build
system now).

This removes the last pieces of shared/OpenglOsUtils
which were never used since the code in render_api.cpp always
used thread-based rendering, instead of process-based one.
This feature could be re-implemented in the future, if really
desirable.

This patch slightly modifies the build files for the GPU emulation
libraries to prepare for future changes in the emulator-specific
build system that will be necessary to support Win64 binaries.
The main difference is the introduction of 64-bit versions of the
emugl-begin-host-<type> macros, named emugl-begin-host64-<type>.

These warnings appear when building the sources through the emulator's
standalone build system, not the platform one.

This patch improves the build files for the GPU emulation
libraries to allow them to be built directly with the emulator's
own standalone build system.

Final patch to completely remove dependencies on
libcutils/libutils/liblog from the host-side GPU
emulation libraries.

This removes dependencies on two libutils headers.
Rather than provide alternative data types, simply disable the
corresponding code because it looks like the corresponding fields
are simply never used by the code?
It is likely that this code is only used in the guest portion
of the code, and thus completely un-necessary on the host side.

Replace it with a custom emugl::IdToObjectMap template
class that owns the objects, simplifying the code.

This remove the use of android::Vector<> by providing an
alternative vector implementation (emugl::PodVector<>) which
is heavily based on the emulator version under
external/qemu/android/base/containers/PodVector.h.
Ultimately the GPU emulation libraries will move under
external/qemu/, and the code will be changed to use
android::base::PodVector<> instead of emugl::PodVector<>.

Remove the dependency on <cutils/sockets.h> by providing
"emugl/common/sockets.h" instead, which contains similar
utility wrappers.

This patch removes the dependency on android::Mutex from
<cutils/threads.h> by providing a custom implementation, which
is a simple wrapper around pthread_mutex_t / CriticalSection,
under shared/emugl/common/mutex.h
+ Provide unit tests.

This gets rid of two copies of SmartPtr.h and replaces them with
a single implementation under shared/emugl/common/smart_ptr.*
Note that this uses a new include path rooted at the shared/
directory for classes that are likely to be built both for
the host and the device (in case we back-port this to
device/generic/goldfish/opengl/ in the future).
+ Add a gtest-based set of unittests, after building, just
call 'emugl_common_host_unittests' to run it.
Note that this probably needs a 64-bit version as well,
will come later once I find a way to build GTest for 64-bits
without breaking the platform build :-)
Also note that this moves the class to the 'emugl' namespace,
in order to make the code easier to build out of the platform
tree, and embed it in other projects. More classes will be
transitioned / refactored in future patches.

Updating or deleting data associated with a buffer object was clearing
the name->data association, but not actually deallocating the data.
Thanks to manjian2006 for finding the bug and proposing the fix.

Previously we used a hardcoded address (tcp port, unix pipe path,
etc.) for the OpenGLRender system. Multiple emulators would all try to
listen on the same address, with the system non-deterministically (?)
choosing which one accepted each new connection. This resulted in
frames going to the wrong emulator window, one emulator shutting down
another's OpenGL system, etc.
Now the OpenGLRender server requests an unused tcp port or derives a
path from the pid, and reports the address back to the emulator client
to use for future connections from the guest.

Because of the way the SDK and Android system images are branched,
host code that goes into the SDK tools can't live in the same
repository as code that goes into the system image. This change keeps
the emugl host code in sdk.git/emulator/opengl while moving the emugl
system code to development.git/tools/emulator/opengl.
A few changes were made beyond simply cloning the directories:
(a) Makefiles were modified to only build the relevant components. Not
doing so would break the build due to having multiple rule
definitions.
(b) Protocol spec files were moved from the guest encoder directories
to the host decoder directories. The decoder must support older
versions of the protocol, but not newer versions, so it makes
sense to keep the latest version of the protocol spec with the
decoder.
(c) Along with that, the encoder is now built from checked in
generated encoder source rather than directly from the protocol
spec. The generated code must be updated manually. This makes it
possible to freeze the system encoder version without freezing the
host decoder version, and also makes it very obvious when a
protocol changes is happening that will require special
backwards-compatibility support in the decoder/renderer.
(d) Host-only and system-only code were removed from the repository
where they aren't used.
(e) README and DESIGN documents were updated to reflect this split.
No actual source code was changed due to the above.

The emulator GLES support has two interfaces: a host shared library
interface used by QEMU, and a protocol between the platform and the
host. The host library interface is not versioned; QEMU and the GLES
renderer must match. The protocol on the other hand must be backwards
compatible: a new GLES renderer must support an older platform image.
Thus for branching purposes it makes more sense to put the GLES
renderer in sdk.git, which is branched along with qemu.git for SDK
releases. Platform images will be built against the protocol version
in the platform branch of sdk.git.
