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 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.

Patrick Lam 61571f3f2e Pass around FcCache *s to the Unserialize functions for extra consistency
(and less overhead, for what that's worth).

Patrick Lam 7fd7221e68 Add *NeededBytesAlign(), which overestimates the padding which is later
added by the new ALIGN macro. Fix alignment problems on ia64 and s390
    by bumping up block_ptr appropriately. (Earlier version by Andreas
    Schwab).
Use sysconf to determine proper PAGESIZE value; this appears to be
    POSIX-compliant. (reported by Andreas Schwab)

Patrick Lam 5e678e9459 Only load requested fonts for fc-cache, and cleanup memory handling:
*Serialize no longer mutates original FcPatterns, it creates a new copy
    in the supplied buffer. Fix thinkos in global cache freeing and in
    FcCacheSkipToArch.

Patrick Lam 7f37423d8c Replace FcObjectStaticName by FcStrStaticName. Implement serialization of
'object' table (strings pointed to by FcPatternElt->object and used as
    keys) and loading of object table from cache file if more strings are
    present in cache file than in current version of fontconfig. Hash the
    object table in memory.

Patrick Lam 4262e0b385 Overhaul the serialization system to create one mmapable file per directory
and distribute bytes for each directory from a single malloc for that
    directory. Store pointers as differences between the data pointed to
    and the pointer's address (s_off = s - v). Don't serialize data
    structures that never actually get serialized. Separate strings used
    for keys from strings used for values (in FcPatternElt and FcValue,
    respectively). Bump FC_CACHE_VERSION to 2.

Patrick Lam 212c9f437e #ifdef out old cache stuff, replace with first version of new mmapping
cache. Add *Read and *Write procedures which mmap in and write out the
    fontconfig data structures to disk. Currently, create cache in /tmp,
    with different sections for each architecture (as returned by uname's
    .machine field. Run the fc-cache binary to create a new cache file;
    fontconfig then uses this cache file on subsequent runs, saving lots of
    memory. Also fixes a few bugs and leaks.

Patrick Lam cd2ec1a940 Add functionality to allow fontconfig data structure serialization.
This patch allows the fundamental fontconfig data structures to be
    serialized. I've converted everything from FcPattern down to be able to
    use *Ptr objects, which can be either static or dynamic (using a union
    which either contains a pointer or an index) and replaced storage of
    pointers in the heap with the appropriate *Ptr object. I then changed
    all writes of pointers to the heap with a *CreateDynamic call, which
    creates a dynamic Ptr object pointing to the same object as before.
    This way, the fundamental fontconfig semantics should be unchanged; I
    did not have to change external signatures this way, although I did
    change some internal signatures. When given a *Ptr object, just run *U
    to get back to a normal pointer; it gives the right answer regardless
    of whether we're using static or dynamic storage.
I've also implemented a Fc*Serialize call. Calling FcFontSetSerialize
    converts the dynamic FcFontSets contained in the config object to
    static FcFontSets and also converts its dependencies (e.g. everything
    you'd need to write to disk) to static objects. Note that you have to
    call Fc*PrepareSerialize first; this call will count the number of
    objects that actually needs to be allocated, so that we can avoid
    realloc. The Fc*Serialize calls then check the static pointers for
    nullness, and allocate the buffers if necessary. I've tested the
    execution of fc-list and fc-match after Fc*Serialize and they appear to
    work the same way.
