22fceefcf070a0cf89bf1846bee16a9d36ad4161 by Derek Mauro <dmauro@google.com>:

Use function static for once initialization of flag registry.

This is a workaround for the MSVC debug constexpr initialization issue
in absl::once_flag.

GitHub #304

e72640ee079b9fa44e2c7f925fa0a608bcfea515 by Derek Mauro <dmauro@google.com>:

Re-write flags config. It doesn't have to be written in the convoluted
way it currently is in the opensource-only code path.

2a72552511b8086c78cb43012c1644e519b3807e by Abseil Team <absl-team@google.com>:

Handle pthread_getschedparam() failure.

Log an error message if pthread_getschedparam() fails.

In Android's Media Framework, libminijail (which I believe is a sandbox)
aborts the process if pthread_getschedparam() is called:

  media.swcodec: libminijail[7526]: blocked syscall: sched_getparam
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  /system/bin/tombstoned: received crash request for pid 7526

Although this CL cannot handle that extreme failure mode, it handles an
error return from pthread_getschedparam() and won't use the uninitialized
param.sched_priority value in that case.

Allow intrinsic int128 to be set for __aarch64__ targets.
