9a8270f427 mdbx: backport - ITS#7682 F_NOCACHE: Allow error, skip any O_DIRECT. 
We can run without F_NOCACHE if it fails. And we do not know
what combining it with O_DIRECT means, if a system has both.

c25b01b5b6 mdbx: backport - reset cursor EOF flag in cursor_set (ITS#8489). 
It usually gets done anyway, but one of the fastpath shortcuts
bypassed this step.

3befcdab01 mdbx: backport - ITS#8209 fix MDB_CP_COMPACT. 
Handle errors.  Fix cond_wait condition so mc_new
is the sole control var.  Drop specious cond_waits.
Do not look at 'mo' while copythr writes it.

Preserve DB flags (use metapage#1) when main DB is empty.
Fail if metapage root != actual root in output file.

Some _aligned_malloc() doc seems to think arg NULL = user error.
Don't know if posix_memalign() pointer is defined after failure.

2806453b54 mdbx: backport - ITS#8339 Solaris 10/11 robust mutex fixes. 
Check for PTHREAD_MUTEX_ROBUST_NP definition (this doesn't work
on Linux/glibc because they used an enum). Zero out mutex before
initing.
