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.

Correct a problem that was causing an apparent directory to be reported as a file instead of a directory by opendir.
...
This happened after adding these three new procfs entries:
fs/block
fs/mount
fs/usage
Of course, there is no directory fs in this case, only three files that have fs/ in their relative pathnames. The logic was detecting that fs was the name of the enty to report, but it was then declaring that fs was a file (because fs/block is of type file).
This was fixed by adding a check for matching lenghts. i.e., if strlen(fs) != strlen(fs/block), then report fs as a directory instead of a file.
