Alexander Larsson c42402d0b8 Cache: Rewrite relocated paths in earlier
This changes the rewriting of the FC_FILE values for relocated caches to an earlier stage
while reading the cache. This is better, because it means all APIs will report the
rewritten paths, not just the once that use the list apis.

We do this by detecting the relocated case and duplicating the FcPattern and FcPatternElm
in an cache allocation (which will die with the cache) and then reusing the FcValueLists
from the cache.

This means that in the rewritten case we will use some more memory, but not the full
size of the cache. In a test here I had 800k of relocated caches, but ~200k of wasted
on duplicating the objects.

This should fix https://bugs.freedesktop.org/show_bug.cgi?id=106618

This may breaks the cache but not bumping in this change sets at this moment.

Akira TAGOH 7587d1c99d Bug 27765 - FcMatch() returns style in wrong language
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.

Behdad Esfahbod 03dcaaa08f Document when config can be NULL (#17105)
Note that this also fixes a bug with FcFontList() where previously
it was NOT checking whether the config is up-to-date.  May want to
keep the old behavior and document that ScanInterval is essentially
unused internally (FcFontSetList uses it, but we can remove that
too).

Behdad Esfahbod 2987409853 Implement fc-list --verbose (#13015)
A private FcObjectGetSet() is implemented that provides an
FcObjectSet of all registered elements.  FcFontSetList() is
then modified to use the object set from FcObjectGetSet() if
provided object-set is NULL.

Alternatively FcObjectGetSet() can be made public.  In that
case fc-list can use that as a base if --verbose is included,
and also add any elements provided by the user (though that has
no effect, as all elements from the cache are already registered).
Currently fc-list ignores user-provided elements if --verbose
is specified.

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 e77c17184a Reinstate basename patch, but keep a hash table linking FcPatterns to their
fully-qualified font names for clients' benefit. Clients only pay for
    the font names once they request the FC_FILE property from an
    FcPattern, but the font name is malloc'd at that point (i.e. not
    mmapped: that's impossible, since it may vary between machines.)
    Clients do have to pay for a copy of the path name per cache file.
Note that FcPatternGetString now does some rewriting if you ask for an
    FC_FILE, appending the pathname as appropriate.

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 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.
