Conf files had an initial comment mentioning the files' name.
This was outdated and wrong in most cases.  There's no real use in that.

Times, Helvetical, and Courier are already handled in 30-metric-aliases.conf.
Remove them here and add a comment instead.

These two names are typos of the correct names. Instead of simply changing
them, the correct thing to do is leave them in the library, add the correct
functions and mark them as deprecated so any source packages will be updated.

This requires bumping the minor version of the library (for adding APIs)
instead of bumping the major version of the library (for removing APIs).

<parameter>ls</function> needed to be <parameter>ls</parameter>.

Just adding the .fncs versions doesn't get these files generated.

These functions no longer exist.

without updating anything.

The old per-user cache filename is no longer used.

FcStrCopyFilename constructs a canonical path for any argument, including
expanding leading ~ and editing '.' and '..' elements out of the resulting
path.

Add check-missing-doc script to make sure the documentation matches the
complete list of symbols exported from the header files before release.

Cache file mtime is meaningless now that the directory time is encoded in
the cache.

Errors in the documentation can be hard to find unless the tool outputs the
line number where the problem exists.

Fix typo errors (Inverval indeed).
Remove FcPattern *p from FcValue (unused)
Remove spurious FcPublic from formals.

Allow file_stat to be NULL by using a local stat structure in that case.

FcFileScan and FcDirScan will skip fonts under direction of the
configuration and default fontconfig policy.

FcConfigUptoDate only checks whether files have been modified since the
configuration was created. Any changes to the configuration through the API
since then are not considered.

fcprivate.h was supposed to extend the fontconfig API for the various
fontconfig utilities. Instead, just have those utilities use the internal
fcint.h header file (which they already do), removing fcprivate.h from the
installation and hence from the defacto public API.

FcAtomicLock can only be called once from any process.

This makes creating "same" aliases for renamed font families far easier.

This makes the --sort and regular output the same for each font.

Checking only config files and font directories can miss changes which
affect only a configuration directory. Check those to catch any changes.

Solaris 10 with GCC doesn't appear capable of supporting the symbol
visibility stuff, so disable it.
