8c255fb1 moved some code out of switch
but did not declare 'buffer'. Also, replacing the "break" with
"goto bail" neglected the WIN32 specific code.

the default language is referred from the FC_LANG environment variable
or the current locale

try to fallback if FC_LANG, LC_ALL, LC_CTYPE and LANG is empty

Add a new API FcGetDefaultLangs() to export the string sets of the default
languages.

It's introduced by 0ac6c982.
Use lstat() and S_ISDIR() to check if it's the directory or not
if there are no d_type in struct dirent.

Windows does not update mtime of directory on FAT filesystem when
file is added to it or removed from it. Fontconfig uses mtime of
directory to check cache file aging and hence fails to detect
newly added or recently removed files.

This changeset detects FAT filesystem (currently implemented for
Linux) and adds generating checksum of directory entries instead
of using mtime which guarantees proper cache rebuild.

For non-FAT filesystems this patch adds single syscall per directory
which is negligeable overhead.

This fixes bug https://bugs.freedesktop.org/show_bug.cgi?id=25535

just rework to share the efforts between FcIsFsMmapSafe() and FcIsFsMtimeBroken().

FcStat() logic is quite complicated in presence of various semi-broken operating
systems and filesystems, split it out in order to make it a bit easier.

link(2) might be failed on the filesystem that doesn't support
the hard link. e.g. FcAtomicLock() always fails on FAT filesystem
when link(2) is available.
So that may be a good idea to fallback if link(2) is failed.

Warn if the multiple values is set to <test>, including the case of
in <alias> because the behavior isn't intuitive since so many users
is asking for a help to get things working for their expectation.

Use multiple <match>s or <alias>es for OR operator and
multiple <test>s for AND operator.

Enclose the string with <string> in <test>

Allows reading configuration files, fonts and cache files from
the directories where the XDG Base Directory Specification defines.

the old directories are still in the configuration files for
the backward compatibility.

Add a new attribute `ignore-blanks' to <test>.
When this is set to "true", any blanks in the string will be ignored
on comparison.  This takes effects for compare="eq" or "not_eq" only.

Also changed the behavior of the comparison on <alias> too.

FC_MAX is also available in src/fcint.h

Since the binding is affected to the score, the replacement should
have same binding to avoid the unexpected estimation.

This patch isn't really tested as I don't have such a machine, but I
have a bug report that on m68k machines, double values are aligned on
smaller than 4 byte boundaries. If ALIGNOF_DOUBLE < sizeof(int),
the "expected" sizeof of FcValue is miscomputed. Use the maximum of 4
(sizeof (int)) and ALIGNOF_DOUBLE when computing the expected size of
FcValue.

Stop using mmap() if the cache file is stored on NFS.
also added FONTCONFIG_USE_MMAP environment variable to enforce the use of
or not the use of mmap(2) regardless of what the filesystem the cache files
are stored on.

Add "namelang" object to obtain the localized name in the font regardless
of the lang object. it's applied to "familylang", "stylelang" and
"fullnamelang" alltogether. this would helps if one wants to enforce
selecting them in the specific language if any.  the default value for
the namelang object is determined from current locale.

Disable iconv support by default, which provide a feature to convert
non-Unicode SFNT names to UTF-8.

Create CACHEDIR.TAG when fc-cache is run or only when the cache directory is created at the runtime.

Also add FcCacheCreateTagFile() API to do create CACHEDIR.TAG on the cache
directory.

Given that fontconfig will scan all of the cache file data during the
first font search, ask the kernel to start reading the pages right away.
