render/gles2: save/restore EGL context in destroy_buffer 
It can be surprising that destroying a buffer changes the EGL context,
especially since this can be triggered from anywhere wlr_buffer_unlock
is called.

Prevent this from happening by saving and restoring the EGL context.

1d461687d2 render/egl: replace init/finish with create/destroy

render/gles2: fix EGL use-after-free 
The wlr_egl was cleaned up too early.

While at it, also fix a memory leak.

26af316b3b render/gles2: make wlr_gles2_texture_from_* private 
These functions are unused by compositors (see e.g. [1]) and prevent
wlr_gles2_texture from accessing wlr_gles2_renderer state. This is an
issue for proper teardown [2] and for accessing GLES2 extensions.

e91417ea8d render: stop making EGL context current in wlr_egl_init 
This leaves an EGL context current behind. wlr_gles2_renderer_create was
assuming the EGL context was already current because of this (because it
called a GL function right off the bat).

1edc42157b render/egl: introduce wlr_egl_unset_current

c682d97841 Return failure of wlr_renderer_init_wl_display() 
This makes it easier for the user of this library to properly handle
failure of this function.

The signature of wlr_renderer_impl.init_wl_display was also modified to
allow for proper error propagation.

515679e4fe Refactor EGL/GL API loading 
Remove glapi.sh code generation, replace it with hand-written loading
code that checks extension strings before calling eglGetProcAddress.

The GLES2 renderer still uses global state because of:

- {PUSH,POP}_GLES2_DEBUG macros
- wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer

85a2ee6d30 render/gles: Simplify textures a bit 
We don't need our own enum for types. Instead we just use
GL_TEXTURE_{2D,EXTERNAL_OES}, which already describes usage.

Also fixes a situation where we were using GL_TEXTURE_2D in a situation
we should not have. wl_drm buffers are always GL_TEXTURE_EXTERNAL_OES,
no matter if they're RGB or any other format.

render/gles2: remove assumptions about supported formats 
We were assuming GL_BGRA_EXT was always supported.

We now check that it's supported for rendering. We fail if it isn't because
this format is specified as "always supported" by the Wayland protocol.

We also check if it's supported for reading pixels. A new preferred_read_format
function returns the preferred format that can be used to read pixels. This is
used by the screencopy protocol.
