MFC r219041:

ktrace_resize_pool() locking slightly reworked:
1) do not take a lock around the single atomic operation.
2) do not lose the invariant of lock by dropping/acquiring
   ktrace_mtx around free() or malloc().

MFC r219042:

Introduce preliminary support of the show description of the ABI of
traced process by adding two new events which records value of process
sv_flags to the trace file at process creation/execing/exiting time.

MFC r219311:

Partially rework r219042.
The reason for this is a bug at ktrops() where process dereferenced
without having a lock. This might cause a panic if ktrace was runned
with -p flag and the specified process exited between the dropping
a lock and writing sv_flags.

Since it is impossible to acquire sx lock while holding mtx switch
to use asynchronous enqueuerequest() instead of writerequest().

Rename ktr_getrequest_ne() to more understandable name.

MFC r219312:

Fix indentation in comment, double ';' in variable declaration.
