Compare Rust definitions against Hexagon SDK 6.4.0.2 computev69 POSIX headers and fix mismatches. Changes pthread_rwlock_t and pthread_rwlockattr_t to *mut c_void, sigval from struct to union, closedir param from *const to *mut DIR. Removes functions not provided by QuRT (fork, execve, kill, alarm, pause, sigprocmask, sigpending, creat). Adds sched_yield, SIGIOT, SIGPOLL; removes SIGVTALRM. Also adds test_qurt() ctest function (disabled — requires sched_yield stub), libc-test/semver/qurt.txt, and fixes the c_schar ambiguous glob re-export.
Add all pthread functions declared in the QuRT SDK pthread.h and
pthread_types.h: thread cancellation, scheduling, spinlocks, barriers,
rwlocks, and various attribute get/set functions. Moves
pthread_attr_{get,set}stack from mod.rs to pthread.rs.
Add POSIX message queue bindings from QuRT's mqueue.h: mq_attr struct, mq_open/close/send/receive and friends, select, pselect.
Add timer_create, timer_delete, timer_gettime, and timer_settime from QuRT's time.h POSIX timer API.
Add process/file functions from QuRT's hooks/unistd.h: getppid, getpgid, getpgrp, setsid, get/set uid/gid variants, fsync, pathconf.
