Add a hash function that behaves like family
comparison: ignoring case and blanks. This
will be used to replace the list walking for
finding family matches with a hash table.
Make variants of FcStrCaseWalkerNext for the two
common cases, delim == NULL and delim == " ", to
speed things up.
These are inner loops, and having the conditions
as simple as possible helps.
As far as I can tell, fontconfig can recover from encountering an unknown attribute.
And unknown elements already print a warning instead of an error, so let's make this a warning too.
"fontversion" used to be modified to sort out fonts as a technique.
But that lost the original purpose to do the version control between
releases.
This change adds the dedicated property into the cache.

mtime isn't reliable to detect updates of fonts on OSTree based system
since they reset mtime to 0 for system files.
Due to this, there are the situation likely to happen where mtime is
newer but content is older.
Fortunately, OSTree based system requires reboot to deploy changes. so
we can assume we won't see any changes on system fonts. so system caches
are always up-to-date. we can ignore meta data for system fonts in
user caches.
XML tools interpret “fonts.dtd” as a relative path.
Unfortunately, that can not work now that the configuration is spread over
multiple system-dependant directories, without a common relative path to this
file. And, an absolute path can not be defined in a system-independant way.
System independance is a requirement to share config files between systems.
Therefore, replace the broken relative path by a formal URN, that will work the
same way on all systems, without network access.
This makes the DTD registerable with commands like:
$ xmlcatalog --noout --add system \
"urn:fontconfig:fonts.dtd" \
"file:///usr/share/xml/fontconfig/fonts.dtd" \
/etc/xml/catalog
That enables easy config file checking:
$ xmllint --loaddtd ${config_file} >/dev/null
The previous fix in fbc05949ef was wrong. reverting.
When reading older caches, FcDirCacheMapHelper() returns FcFalse and
it became the return value from FcDirCacheProcess() too, which is wrong.
Actually one of calls for FcDirCacheMapHelper() should be successfully
finished and closure should have a valid pointer for cache.
Due to this, the proper finalization process wasn't running against
cache in closure.

iPhone 2.1 was released a long time ago, and the macro for checking
the target iOS SDK version has changed. We can simplify everything and
do a very basic check.
Due to the unproper initialization of `latest_mtime', the duplicate caches
was still in fcCacheChains with no references. which means no one frees
them. thus, the memory leak was happened.
Fixes https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/227
Right now fontconfig uses a cache found first in a path and
cachedirs are the order of the system-wide path and then the user path.
this is due to avoid writing caches into the user path when running as root.
However, changing caches by certain config only, e.g. using <match target="scan">
may not take effect by this behavior, because it may be stored into the user path.
Thus, needing to find the latest cache out from paths.

When loading the default config file with FONTCONFIG_SYSROOT,
it fails if no /etc/fonts/fonts.conf is available, even if it is
there where is based on sysroot.
To address this, FcConfig is required to determine the sysroot.
therefore, this change makes FcConfigFilename() deprecated,
use FcConfigGetFilename() instead.
Fixes https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/181
cachedir is used to determine where cache files are stored.
the empty directory will ends up to put them under the top of
directory of XDG_CACHE_HOME. that messes it up and must be avoided.
As a note, if you want to read/write something from the top of
XDG_DATA_HOME (dir) and/or XDG_CACHE_HOME (cachedir),
put "." instead of the empty.
