2018-09-12reduce spurious inclusion of libc.hRich Felker1-0/+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.
2017-04-21fix regression in support for resolv.conf attempts optionRich Felker1-2/+2
commit d6cb08bcaca4ff1f921375510ca72bccea969c75 moved the code and introduced an incorrect string offset for the new parsing, probably due to a copy-and-paste error. patch by Stefan Sedich.

2016-01-28factor resolv.conf parsing out of res_msend to its own fileRich Felker1-0/+93
this change is made in preparation for adding search domains, for which higher-level code will need to parse resolv.conf. simply parsing it twice for each lookup would be one reasonable option, but the existing parser code was buggy anyway, which suggested to me that it's a bad idea to have two variants of this code in two different places. the old code in res_msend potentially misinterpreted overly long lines in resolv.conf, and stopped parsing after it found 3 nameservers, even if there were relevant options left to be parsed later in the file.
