COARSE clocks add a worst-case jitter of 10ms to the timing, as they
degrade the timing to Linux jiffy accuracy. However, they allow to skip
a syscall on platforms where the accurate version of the clock can not
be accelerated through the VDSO.
Switch to using the COARSE version of the clock when the timeout is
larger than 200ms, i.e. the accuracy of the timeout is degraded less
than 5% by the added worst-case jitter.

By using the the COARSE variant of the clock we can avoid a syscall
to fetch the current time on platforms where the more accurate
version of the clock can not be accelerated through the VDSO. The
most relevant platform with this restriction is ARM32 without the
architected timer extension, e.g. the NXP i.MX6.
The COARSE clock degrades the accuracy of the timing to Linux
jiffies, which means it adds a worst-case jitter of 10ms, which is
basically noise in relation to the 1sec holding time of the cache
and the irregular call pattern of etna_bo_cache_cleanup().

Currently the buffer index hash is only used if the BO is used in
multiple streams and the current index is cached on the BO. This
introduces some shared state on the BO, which necessitates the use
of a lock to keep this state consistent across threads, which
negates some of the benefits of caching the index.
Always use the hash to keep track of the submit BOs, to get rid
of the shared state and simplify the code.

~128KB. Fix this by using the proper limit in dwords.
Flushing due to some limits being exceeded is not an issue, but is

Android.mk files haven't really been supported by Mesa devs for a long
time. Most of us have been willing to update Makefile.sources if we
remember and sometimes we try to blind code some Android.mk for a new
generator. However, the reality is that it breaks regularly and ends up
being maintained by the Android community. To address this problem
another approach was implemented in !10183 utilizing the maintained
meson build system. The old Android.mk files are no longer required.
This commit was created with the following commands:
