Move pthread-specific data into TLS 1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread. 2. Remove pthread-specific data functions from syscalls. 3. Implement tls_alloc() and tls_free() with system calls. 4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free(). 5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()

This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT. Squashed commit of the following: Add procfs support to show stopped tasks. Add nxsig_action() to solve a chicken and egg problem: We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored. sched/signal: Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT. Fix some compilation issues. sched/sched: Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state. I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error. sched/group and sched/sched: Finish framework for continue/resume logic. sched/signal: Roughing out basic structure to support task suspend/resume

binfmt/ and sched/group: Re-architect the way that loadable ELF or NXFLAT modules are unloaded. Memory resources must be recovered when the task loaded into memory exits. The originmal implementatino used the death-of-child SIGCHLD signal to perform the unload. There are several problems with this: It is overly complex, it requires that the parent task stay resident while the loaded task runs, and it has fatal logic flaws in the protected and kernel model builds because the user signal handler attempts to run in the kernel address space. This commit corrects with using a mindlessly simply BINFMT callback when the task exits.

Revert "tls: Move pthread key destructor to libc" This reverts commit cc514d7791dae0808124249ff545d9dda39b24b7. * It introduced a regression. https://github.com/apache/incubator-nuttx/issues/3868 * It seems conceptually wrong to have per-process data in the main thread's stack.
