GDB looks for specific opcode sequences when trying to recognize a stack
frame as a signal trampoline. The sequences it looks for happen to be those
created when SA_RESTORER is set, since glibc always sets a restorer. This
patch does the same here, so that the trampolines can be correctly identified.

Note that this does not change the implementation of conditional variables
which still use shared futexes, independent on the flags being selected.
This will be fixed in a later patch, once our system is modified to use
pthread_condattr_setpshared(attr, PTHREAD_PROCESS_SHARED) properly.

dladdr() is a GNU extension function, which allows the caller to retrieve
symbol information for a specified memory address. It is useful for things
like generating backtrace information at runtime.

Private futexes are a recent kernel addition: faster futexes that cannot be
shared between processes. This patch uses them by default, unless the PROCESS_SHARED
attribute flag is used when creating a mutex and/or conditional variable.
Also introduces pthread_condattr_init/destroy/setpshared/getpshared.

Any of the setuid functions now updates /acct/uid/ with its own tid
before changing users. This is so we can properly account for cpu time
per uid.

Only provide an implementation for ARM at the moment, since
it requires specific assembly fragments (the standard syscall
stubs cannot be used because the child returns in a different
stack).
The gHardy man pages specify the return type of ptsname_r to be char*, but the
return value to be 0 on success, negative on error and the gHardy stdlib.h
defines extern int ptsname_r(...).
Busybox telnetd fails to run successfully without this change.

This reverts commit 754c178ae5.
Turns out we don't need it afterall (needed a stable sort anyways).
So, we'll make that change in the dev branch instead.

NOTE: This replaces qsort.c with the FreeBSD version. While
the patch changes the source, it should not alter the
implementation that should use the exact same algorithm.
Wrapped declarations in time64.h with __BEGIN_DECLS/__END_DECLS so that
the prototypes are correctly identified as extern C.

This is used to perform a mutex lock for a given amount of
milliseconds before giving up. Using the _np prefix since this
is absolutely not portable.
Also remove a compiler warning in pthread_attr_getstackaddr
Compiling with -std=c99 defines __STRICT_ANSI__, but the 64 bit types
and type macros should still be defined in this case.
This helps compiling third party code that needs -std=c99 with the NDK.
