[TSan] Defer symbolization in AddStack and AddSleep to SymbolizeStackElems
PR #151495 delayed symbolization for memory accesses, locations,
threads, and mutexes until OutputReport (after ThreadRegistryLock is
released), but missed ScopedReport::AddStack and ScopedReport::AddSleep.
As a result, ReportRace (via AddSleep) and ReportMutexMisuse,
ReportDeadlock, and ReportDestroyLocked (via AddStack) still invoked the
symbolizer while holding ThreadRegistryLock.
Store the unsymbolized stack traces and sleep stack ID in ReportDesc and
symbolize them in ScopedReport::SymbolizeStackElems().

[NFC][TSan] Move ObtainCurrentStack out of ThreadRegistryLock scope
ObtainCurrentStack only reads the current thread's shadow stack and
allocates a VarSizeStackTrace buffer, which does not require
ThreadRegistryLock (and already runs outside ThreadRegistryLock in
ReportRace, SignalUnsafeCall, ReportErrnoSpoiling, and
ReportDestroyLocked).
Move ObtainCurrentStack (and dummy_pc in ReportDeadlock) before
ScopedReport in ReportMutexHeldWrongContext, ReportMutexMisuse, and
ReportDeadlock so the stack trace buffers also outlive ScopedReport and
OutputReport.

[NFC][TSan] Move RestoreStack before ScopedReport in ReportDestroyLocked
Run RestoreStack in its own lock scope before constructing ScopedReport
in ReportDestroyLocked (matching ReportRace). This avoids acquiring
ScopedErrorReportLock or symbolizing the current stack if RestoreStack
fails, and avoids holding slot_lock and slot_mtx while populating the
ScopedReport.

nfscl: Add support for b_pages to be used by RDMA
This patch updates the NFS client RDMA glue so that I/O
can be done directly to/from b_pages for buffer cache
blocks.
It also adds a flag to disable read reduction, that might
be needed against some non-FreeBSD servers and sets readahead
to 8 for RDMA unless the "readahead" option has been
specified.
This commit should not affect non-RDMA behaviour.
