* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-131/+122
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.

| | | | | | | | | for FILEs that don't have real file-descriptors: the fake FILEs used internally by snprintf/asprintf/vfprintf and friends now avoid unnecessary locking by calling the internal __vfprintf() routine directly and we do want to do locking on FILEs created with funopen(). ok kurt@
