src/lib/libc/stdlib/strtol.c, branch releng/13.1

Move strtold wrapper from strtol.c to its own strtold.c. This code

was written by theraven@ (David Chisnall) entirely, there's no
original Berkeley code left here so just copy his copyright over.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47+00:00

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Renumber clauses to reduce diffs to other versions

2013-06-13T00:19:30+00:00

NetBSD, OpenBSD, and Android's Bionic number the clauses 1 through 3,
so follow suit to make comparison easier.

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a

2011-11-20T14:45:42+00:00

load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter.  Also
adds support for per-thread locales.  This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

POSIX says that 0[xX] prefix is _optional_ even in base 16 case, make it

2005-01-21T00:42:13+00:00

really so.

"If the value of base is 16, the characters 0x or 0X may optionally
precede the sequence of letters and digits, following the sign if
present."

Style: One space between "restrict" qualifier and "*".

- Add the 'restrict' qualifier to the function prototypes and

2002-08-15T09:25:04+00:00

   definitions of the functions that convert strings to numbers
   and are defined by IEEE Std 1003-1.2001.
 - Use ANSI-C function definitions for all of the functions
   mentioned above plus strtouq and strtoq.
 - Update the prototypes in the manual pages.

Fix the style of the SCM ID's.

I believe have made all of libc .c's as consistent as possible.
