Akira TAGOH c20ac78b01 Bug 57114 - regression on FcFontMatch with namelang
After 7587d1c99d applied, family,
style, and fullname is localized against current locale or lang
if any though, the string in other languages were dropped from
the pattern. this caused unexpected mismatch on the target="font"
rules.

This fix adds other strings at the end of the list.

Akira TAGOH 4a060729a1 fcpat: Increase the number of buckets in the shared string hash table
This is a reasonably conservative increase in the number of buckets in the hash
table to 251.  After FcInit(), there are 240 shared strings in use on my system
(from configuration files I assume).  The hash value is stored in each link in
the chains so comparison are actually not very expensive.  This change should
reduce the average length of chains by a factor of 8.  With the reference
counted strings, it should keep the average length of chains to about 2.  The
number of buckets is prime so as not to rely too much on the quality of the
hash function.

Keith Packard 13a14cbf56 Fix a few memory tracking mistakes.
The built-in memory tracking code in fontconfig relies on a lot of manual
function call tracking. A pain, but it helps debug leaks.

Stephan Kulow 9b74b78fe8 Make FcPatternDuplicate copy the binding instead of always using Strong.
I noticed that Qt always uses a different font than fc-match advertises.
Debugging the issue, I found that a call that looks pretty innocent is
changing all weak bindings to strong bindings and as such changes the
semantic of the match: FcPatternDuplicate.

Keith Packard 2b77216ee2 Avoid writing uninitialized structure pad bytes to cache files.
The union inside the FcValue structure contains pad bytes. Instead of
copying the whole structure to the cache block, copy only the initialized
fields to avoid writing whichever bytes serve as padding within the
structure.

Keith Packard 23816bf9ac Eliminate .so PLT entries for local symbols. (thanks to Arjan van de Ven)
Using a simple shell script that processes the public headers, two header
files are constructed that map public symbols to hidden internal aliases
avoiding the assocated PLT entry for referring to a public symbol.

A few mistakes in the FcPrivate/FcPublic annotations were also discovered
through this process

Keith Packard 9e612141df Reference count cache objects.
Caches contain patterns and character sets which are reference counted and
visible to applications. Reference count the underlying cache object so that
it stays around until all reference objects are no longer in use.

This is less efficient than just leaving all caches around forever, but does
avoid eternal size increases in case applications ever bother to actually
look for changes in the font configuration.

Keith Packard bc5e487f2a Pass directory information around in FcCache structure. Freeze charsets.
Instead of passing directory information around in separate variables,
collect it all in an FcCache structure. Numerous internal and tool
interfaces changed as a result of this.

Charsets are now pre-frozen before being serialized. This causes them to
share across multiple fonts in the same cache.

Keith Packard e9a564e2cd Serialized value lists were only including one value.
The next pointer in the serialized value list wasn't getting set, so they
were truncated at a single value.

Keith Packard 09f9f6f62a Rework Object name database to unify typechecking and object lookup.

Keith Packard c02886485b FcCharSetSerialize was using wrong offset for leaves. Make fc-cat work.
FcCharSetSerialize was computing the offset to the unserialized leaf,
which left it pointing at random data when the cache was reloaded.

fc-cat has been updated to work with the new cache structure.

Various debug messages extended to help diagnose serialization errors.

Keith Packard 7ce1967331 Rework cache files to use offsets for all data structures.
Replace all of the bank/id pairs with simple offsets, recode several
data structures to always use offsets inside the library to avoid
conditional paths. Exposed data structures use pointers to hold offsets,
setting the low bit to distinguish between offset and pointer.

Use offset-based data structures for lang charset encodings; eliminates
separate data structure format for that file.

Much testing will be needed; offsets are likely not detected everywhere in
the library yet.
