libc: speed-up flockfile()/funlockfile() For Honeycomb, we added proper file thread-safety for all FILE* operations. However, we did implement that by using an out-of-band hash table to map FILE* pointers to phtread_mutex_t mutexes, because we couldn't change the size of 'struct _sFILE' without breaking the ABI. It turns out that our BSD-derived code already has some support code to extend FILE* objects, so use it instead. See libc/stdio/fileext.h This patch gets rid of the hash table, and put the mutex directly into the sFILE extension. Change-Id: If1c3fe0a0a89da49c568e9a7560b7827737ff4d0

Fix the handle locking in stdio Fix the handle locking in stdio to use flockfile/funlockfile 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. Based on OpenBSD change by guenther@openbsd.org http://www.mail-archive.com/source-changes@cvs.openbsd.org/msg01015.html Bug: 3446659 Change-Id: Ie82116e358c541718d6709ec45ca6796be5a007b

stdio: make internal symbols static/hidden Although header libc/stdio/local.h declares the macros and private variables of stdio, there are several internal symbols exposed unexpectedly. Change-Id: Ie7a07f85b70322fb9cd05b3c8e1bcc416061eb4b
