Privatize headers
Remove most installed headers, which should be internal. The header
kcompat (kernel-style compatibility header) only makes sense within the
UST package: this should never be exported, nor be included into

Move the type-serializer header back into libust/. It is so internal it
does not even belong to include/ust/.

Prefix with _ or __ all members that are internal to UST. Move all the
non-exported API members (that don't need to be around in program
inclusion) to tracepoint-internal.h (which is not meant to be installed

Unit tests can still use the internal API members for now, but should

TRACEPOINT_EVENT is changed from the kernel incarnation (TRACE_EVENT):

Make libustctl list only online pids v3
Changes since v2:
Botox.
Changes since v1:
Cosmetic surgery at a european cost
Previously libustctl would list all pids. This patch changes this
so only online pids are listed. This is done by appending on each
socket name the mtime from the proc/<pid> directory. This way a
socket can be checked to see if the appended mtime matches the
mtime of the proc dir for the current pid, thus allowing us to
distinguish between old and new socket files.

armv5 archs require write alignment
Reads and writes to unsigned int 32 bit numbers must be address
aligned or the l2 cache can return junk in the high order 16 bits on
reads.
This patch activates the original work done for alignment in ltt for
the UST code. The config.ac changes will isolate the use of alignment
to the known arch type with the problem.

add mips support
The recent changes to UST make it trivial to add MIPS support.
The trick for MIPS is that there are many different library formats
and the gcc 4.x compiler will correctly choose the default one so long
as the libust.ldscript.in does not not make a reference to the library
format.

support busybox for manual trace tests
The busybox version of find does not support using -L, and it does not
appear to be needed in order to pass the test. In the interest of
being able to run internal UST tests on a busybox based rootfs,
appropriately detect if -L is available as an argument to find and use
it when it is available.

ust-consumerd: fix exit race log corruption
In the following scenario on an SMP system the ust-consumerd can end
up not properly closing out file handles which leads to log
corruption:
* usttrace -m -l small_quick_app_lots_of_malloc_and_free
* The app completes and usttrace sees and sends the SIGTERM to ust-consumerd
* The ust-consumerd main thread will exit and the _exit() handlers
kills off the remaining pthreads without everything getting closed out
The solution to the problem is to introduce an active_thread count for
the private ustconsumer_instance. This counter will be zeroed out
when it is safe to completely shutdown the main thread, which will
subsequently run the _exit() handlers.

ust-consumerd: fix exit race crashes
The ust-consumerd gets shutdown by the SIGTERM signal and a number of
places in the ust-consumerd did not properly deal with the case where
a system call returns EINTR in errno as a result of a signal to the
process. The failure to handle EINTR properly was leading to some
data corruption in the buffer code and causing some random "victim"
crashes in lowlevel.c
The way all the offending functions were tracked down was to
temporarily add an abort() in the SIGTERM signal handler. Then it was
a matter of looking at what threads were blocked on system calls at
the time outside of the thread that received the signal.

Markers: temporarily remove GDB support
Remove GDB support temporarily, awaiting a better implementation that
does not require so much asm trickery. Imported the kernel LTTng code
back into UST to use C declarations for the marker structures.
The plan is to move to a SDT-based implementation (using variable
number of arguments).
This patch is required to make the MIPS port work. Tested by Jason
Wessel.
