Topic: musl 1.2.4 launched

This launch provides TCP fallback to the DNS stub resolver, fixing the
longstanding incapacity to question giant DNS data and incompatibility
with recursive nameservers that do not give partial ends in
truncated UDP responses. It additionally makes a variety of different bug fixes and
enhancements in DNS and associated performance, together with making each
the fashionable and legacy API outcomes differentiate between NODATA and
NxDomain circumstances in order that the caller can deal with them in a different way.

On the API degree, the legacy "LFS64" ("giant file assist")
interfaces, which had been offered by macros remapping them to their
commonplace names (#outline stat64 stat and comparable) have been deprecated
and are now not offered beneath the _GNU_SOURCE function profile, solely
beneath express _LARGEFILE64_SOURCE. The latter can even be eliminated in
a future model. Builds damaged by this alteration may be mounted short-term
by including -D_LARGEFILE64_SOURCE to CFLAGS, however must be mounted to make use of
the usual interfaces.

The dynamic linker (and static-PIE entry level code) provides assist for
the brand new compact "RELR" format for relative relocations which latest
linkers can generate. Use of this linker function for dynamic-linked
applications will make them rely upon having musl 1.2.4 or later obtainable
at runtime. Static-linkied PIE binaries utilizing it, as at all times, are
self-contained and don't have any such dependency.

A lot of bugs have been mounted, together with many within the large
printf household of capabilities, incorrect ordering of digits vs non-digits
in strverscmp, and several other uncommon race-condition nook circumstances in thread
synchronization logic at thread exit time, in multi-threaded fork,
pthread_detach, and POSIX semaphores.
