Eric Engestrom 54fa5eceae egl: use coherent variable names
`EGLDisplay` variables (the opaque Khronos type) have mostly been
consistently called `dpy`, as this is the name used in the Khronos
specs.

However, `_EGLDisplay` variables (our internal struct) have been
randomly called `dpy` when there was no local variable clash with
`EGLDisplay`s, and `disp` otherwise.

Let's be consistent and use `dpy` for the Khronos type, and `disp`
for our struct.

Rob Clark cce04a4630 egl: initialize SyncCondition after attr parsing
Reduce the noise in the next patch.  For EGL_SYNC_NATIVE_FENCE_ANDROID
the sync condition is conditional on EGL_SYNC_NATIVE_FENCE_FD_ANDROID
attribute.

Chad Versace 8044885182 egl: Unify the EGLint/EGLAttrib paths in eglCreateSync* (v3)
Pre-patch, there were two code paths for parsing EGLSync attribute
lists: one path for old-style EGLint lists, used by eglCreateSyncKHR,
and another for new-style EGLAttrib lists, used by eglCreateSync (1.5)
and eglCreateSync64 (EGL_KHR_cl_event2).

There were two attrib_list parsing functions,
  _eglParseSyncAttribList(_EGLSync *sync, const EGLint *attrib_list)
  _eglParseSyncAttribList64(_EGLSync *sync, const EGLattrib *attrib_list)
This patch unifies the two attrib_list parsing functions into one,
  _eglParseSyncAttribList(_EGLSync *sync, const EGLattrib *attrib_list)

Many internal EGLSync function signatures had *two* attrib_list
parameters to accomodate both code paths: one parameter was an EGLint
list and other an EGLAttrib list. At most one of the parameters was
allowed to be non-null.  This patch removes the `EGLint *attrib_list`
parameter, leaving only the `EGLAttrib *attrib_list` parameter, for all
internal EGLSync functions.

v2:
  - Consistently use condition (sizeof(int_list[0]) ==
    sizeof(attrib_list[0])). [for emil]
v3:
  - Don't double-unlock the display in eglCreateSyncKHR.

Chad Versace add01add1b egl: Drop duplicate check on EGLSync type
_eglInitSync checked that the display supported the sync type (such as
EGL_SYNC_FENCE), and did it wrong. When the check failed it emitted
EGL_BAD_ATTRIBUTE, but sometimes EGL_BAD_PARAMETER is needed.

_eglCreateSync already does the error checking, and it does it right.

Chad Versace 02e4f1cb43 egl: Cleanup control flow in _eglParseSyncAttribList
When the function encountered an error, it effectively returned
immediately. However, it did so indirectly by breaking out of a loop.
Replace the loop breakout with a explicit 'return'.

Do the same for _eglParseSyncAttribList64 too.

Dongwon Kim 70299474f5 egl: add EGL_KHR_reusable_sync to egl_dri
This patch enables an EGL extension, EGL_KHR_reusable_sync.
This new extension basically provides a way for multiple APIs or
threads to be excuted synchronously via a "reusable sync"
primitive shared by those threads/API calls.

This was implemented based on the specification at

https://www.khronos.org/registry/egl/extensions/KHR/EGL_KHR_reusable_sync.txt

v2
- use thread functions defined in C11/threads.h instead of
  using direct pthread calls
- make the timeout set with reference to CLOCK_MONOTONIC
- cleaned up the way expiration time is calculated
- (bug fix) in dri2_client_wait_sync, case EGL_SYNC_CL_EVENT_KHR
  has been added.
- (bug fix) in dri2_destroy_sync, return from cond_broadcast
  call is now stored in 'err' intead of 'ret' to prevent 'ret'
  from being reset to 'EGL_FALSE' even in successful case
- corrected minor syntax problems

v3
- dri2_egl_unref_sync now became 'void' type. No more error check
  is needed for this function call as a result.
- (bug fix) resolved issue with duplicated unlocking of display in
  eglClientWaitSync when type of sync is "EGL_KHR_REUSABLE_SYNC"

Dongwon Kim d1e1563bb6 egl: move Null check to eglGetSyncAttribKHR to prevent Segfault
Null-check on "*value" is currently done in _eglGetSyncAttrib, which is
after eglGetSyncAttribKHR dereferences it.

Move the check a layer up (in the beginning of eglGetSyncAttribKHR) to
avoid segfaults.

There is no point in having them when we distribute eglext.h.

As for unofficial extensions, there is a chance that we might remove some of
them evetually.  Keeping the #ifdef's for now should make that easier.
