do_fork: Increase tid table size when allowing oversubscription
...
The size of tid table needs to be more than #CPUs when CPU oversubscription
is needed.
Note that the max number of simultaneous threads are the min of the
following two:
(1) Number of mcexec worker threads
(2) NR_TID defined in kernel/syscall.c

syscall: move sync_child_event up a bit
...
The function was between two perf functions when perf functions don't
use it...
It seemed simpler to move the function than to add an extra ifdef
Use that occasion to fix style warnings, no actual code changes were
made.

debug messages: implement dynamic debug
...
Heavily inspired off linux kernel's dynamic debug:
* add a /sys/kernel/debug/dynamic_debug/control file
(accessible from linux side in /sys/class/mcos/mcos0/sys/kernel/debug/dynamic_debug/control)
* read from file to list debug statements (currently limited to 4k in size)
* write to file with '[file foo ][func bar ][line [x][-[y]]] [+-]p' to change values
Side effects:
* reindented all linker scripts, there is a new __verbose section
* added string function strpbrk

search_free_space: remove POSTK_DEBUG_ARCH_DEP_27 side
...
search_free_space changed since this was implemented and the code is
no longer compatible
Looking at it again, the function is not used anywhere other than syscall.c
and the second function does not seem to fix anything specific so this
just removes the untested side.
