*	reduce spurious inclusion of libc.h	Rich Felker	2018-09-12	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	libc.h was intended to be a header for access to global libc state and related interfaces, but ended up included all over the place because it was the way to get the weak_alias macro. most of the inclusions removed here are places where weak_alias was needed. a few were recently introduced for hidden. some go all the way back to when libc.h defined CANCELPT_BEGIN and _END, and all (wrongly implemented) cancellation points had to include it. remaining spurious users are mostly callers of the LOCK/UNLOCK macros and files that use the LFS64 macro to define the awful *64 aliases. in a few places, new inclusion of libc.h is added because several internal headers no longer implicitly include libc.h. declarations for __lockfile and __unlockfile are moved from libc.h to stdio_impl.h so that the latter does not need libc.h. putting them in libc.h made no sense at all, since the macros in stdio_impl.h are needed to use them correctly anyway.
*	remove unused #undef environ now that libc.h no longer #defines it	Rich Felker	2013-02-17	1	-1/+0

*	bring back ___environ symbol (3 underscores)	Rich Felker	2011-08-23	1	-0/+1
\| \| \| \| \| \|	its existence doesn't hurt anything, and dynamic-linked binaries using previous versions of musl were wrongly binding to it instead of __environ.
*	security hardening: ensure suid programs have valid stdin/out/err	Rich Felker	2011-08-23	1	-4/+3
\| \| \| \| \| \| \| \| \| \| \|	this behavior (opening fds 0-2 for a suid program) is explicitly allowed (but not required) by POSIX to protect badly-written suid programs from clobbering files they later open. this commit does add some cost in startup code, but the availability of auxv and the security flag will be useful elsewhere in the future. in particular auxv is needed for static-linked vdso support, which is still waiting to be committed (sorry nik!)
*	initial check-in, version 0.5.0 v0.5.0	Rich Felker	2011-02-12	1	-0/+7
