musl 1.1.13 released

[Rich Felker <dalias@libc.org>]

This release adds support for out-of-tree builds, search domains in
resolv.conf, VDSO-accelerated clock_gettime on MIPS, and building
SMP-safe/ready SH binaries for the open-hardware J2. Performance of
atomics and synchronization primitives has been greatly improved on
most "ll/sc model" RISC archs. Regex BRE now supports the widely-used
extensions \|, \+, and \? and larger regular expressions are now
supported. A number of minor application and toolchain compatibility
improvements have also been made, including changes which reduce the
risk of assembler and linker bugs leading to malfunctioning binaries.

Two potentially dangerous bugs have been fixed: a single-byte heap
overflow in getdelim and a pointer indexing error in dynamic TLS
allocation. Other bugs fixed include various issues in parsing and
error handling for resolv.conf and related files, incorrect error
return values for some functions, and failures to accept null pointer
arguments in some functions for which they have defined behavior. Some
arch-specific bugs affecting ARM, MIPS, and SH/FDPIC have also been
fixed.
