Move softfloat symbol map entries to softfloat/Symbol.map.

2018-03-05T20:51:23Z

The arm, mips, and riscv MD Symbol.map files listed some (but not all) of the softfloat symbols that were actually defined in softfloat.c. While here, also remove entries for __fixuns[sd]fsi which are provided by libcompiler_rt and not by libc. Sponsored by: DARPA / AFRL

libc: further adoption of SPDX licensing ID tags.

2017-11-25T17:12:48Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
