New VFS plugin for emulating POSIX pipes Add a new plugin for creating pipes between pairs of VFS handles. It is intended to replace the libc_pipe plugin, one of the last remaining libc plugins. In contrast to the libc_pipe plugin, this plugin defers cross-handle notification until I/O signal handling rather than block and unblock readers using a semaphore. This is a performance regression in the case of multiple threads blocking on a pipe, but shall be an intermediate mechanism pending renovations within the libc VFS and threading layers. As a side effect, threads blocked on a pipe might not be resumed until the main thread suspends and dispatches I/O signals. The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin and tests both local pipes and pipes hosted remotely in the VFS server.
