994a1f78b1 perf tools: Check mmap pages value early 
Move the check of the mmap_pages value to the options parsing time, so
we could rely on this value on other parts of code.

Related changes come in the next patches.

Also changes perf_evlist::mmap_len to proper size_t type.

314add6b1f perf tools: change machine__findnew_thread() to set thread pid 
Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.

Note that callers sometimes want to find the main thread
which has the memory maps.  The main thread has tid == pid
so the usage in that case is:

	machine__findnew_thread(machine, pid, pid)

whereas the usage to find the specific thread is:

	machine__findnew_thread(machine, pid, tid)

04b34729e4 perf trace: Allow printing syscall return values in hex 
event_format->flags has a FIELD_IS_POINTER, but it is not set for
the sys_exit 'ret' field in syscalls like mmap, so we need a way to
ask for hex printing for pointer returns and keep things like 'read'
returns printing in decimal.
