Rich Felker ad2fe25041 support the ugly and deprecated ucontext and sigcontext header stuff... 
only the structures, not the functions from ucontext.h, are supported
at this point. the main goal of this commit is to make modern gcc with
dwarf2 unwinding build without errors.

honestly, it probably doesn't matter how we define these as long as
they have members with the right names to prevent errors while
compiling libgcc. the only time they will be used is for propagating
exceptions across signal-handler boundaries, which invokes undefined
behavior anyway. but as-is, they're probably correct and may be useful
to various low-level applications dealing with virtualization, jit
code generation, and so on...

Rich Felker e9417fffb3 add pthread_atfork interface 
note that this presently does not handle consistency of the libc's own
global state during forking. as per POSIX 2008, if the parent process
was threaded, the child process may only call async-signal-safe
functions until one of the exec-family functions is called, so the
current behavior is believed to be conformant even if non-ideal. it
may be improved at some later time.

Rich Felker 446b4207cc major improvements to temp file name generator 
use current time in nanoseconds and some potentially-random (if aslr
is enabled) pointer values for the initial tempfile name generation,
and step via a cheap linear prng on collisions. limit the number of
retry attempts to prevent denial of service attacks even if an
attacker can guess the filenames.

Rich Felker 3e9e30166f reformat mkstemp like mkdtemp 
this is cleaner and makes it easy to impose a limit on the number of
retries later if it seems desirable to do so.

Rich Felker e882756311 reorganize pthread data structures and move the definitions to alltypes.h 
this allows sys/types.h to provide the pthread types, as required by
POSIX. this design also facilitates forcing ABI-compatible sizes in
the arch-specific alltypes.h, while eliminating the need for
developers changing the internals of the pthread types to poke around
with arch-specific headers they may not be able to test.

Rich Felker b24bc15f5c don't compare elements with themselves during qsort. 
this is actually a workaround for a bug in gcc, whereby it asserts

Rich Felker e3657ba599 patch by njk, simplifies thread register initialization for x86_64 
It's not necessary to save any registers on the stack across syscall in

Rich Felker 9b235e8374 remove standalone syscall cruft 
this was originally written for an early draft of the library where
non-standard functions would reside in a static library separate from
the shared libc.so, which would implement a pure standard. the idea
was not to depend on an implementation-dependent __syscall_ret
function in the main libc. but it turned out to be better to put
everything in a single library for both static and dynamic linking
uses, and thus the (incomplete) remnants of this feature were just
enlarging the source and binary.
