Mike Kaganski f3e7004794 tdf#130725: use strtod by David M. Gay to make sure we get the nearest 
... representation of given decimal.
Use dtoa.c from https://www.netlib.org/fp/dtoa.c to build a custom
static library that doesn't use current locale (unlike strtod from
stdlib.h).  This is the implementation used by e.g. python and nss
(search for "dtoa.c" under UnpackedTarball).

To avoid name clash with the standard strtod, rename the function
to strtod_nolocale.

Size of buffer on stack in ImpSvNumberInputScan::StringToDouble is
256 characters. Logging function usage in make check, of ~124 600
invocations, the longest string was 14 characters, average being
2.1 characters. So heap allocation is unlikely in scenarios with
intensive function usage.

After std::from_chars is available in baseline compilers, external
library can be dropped, and call to strtod_nolocale replaced with
the standard function.

The artifact at https://dev-www.libreoffice.org/src/dtoa-20180411.tgz
is created with

  mkdir dtoa && mkdir dtoa/src && wget https://www.netlib.org/fp/dtoa.c -O dtoa/src/dtoa.c && \
   printf 'd8bab255476f39ea495c8c8ed164f9077da926e6ca7afb9ad3c56d337c4484fe dtoa/src/dtoa.c' | sha256sum -c && \
   tar -c --owner=0 --group=0 --mode=go=r,u=rw --mtime='Wed, 11 Apr 2018 15:59:39 GMT' dtoa/src/dtoa.c | gzip -n > dtoa-20180411.tgz && \
   printf '0082d0684f7db6f62361b76c4b7faba19e0c7ce5cb8e36c4b65fea8281e711b4 dtoa-20180411.tgz' | sha256sum -c

(where the date "Wed, 11 Apr 2018 15:59:39 GMT" is from
`wget -S https://www.netlib.org/fp/dtoa.c`
"Last-Modified: Wed, 11 Apr 2018 15:59:39 GMT" header).
