realfilename is the file name after sysroot adjustments. It should be used
instead of filename in the call to FcOpen() which forwards the name directly to
open().
Though I don't explicitly request a sysroot, I was getting error messages saying
"failed reading config file". This CL fixes the error spam.
The expression "1 << 31" will cause UBSAN to complain with this error message:
runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
The same operation on unsigned types is fine, however. This CL replaces the
strings "1 <<" with "1U <<".
In 161c738 I switched from linear name scanning to binary searching.
That, however, ignored the fact that there might be more than one
name table entry for each pair we want to query.
To fix that and retain bsearch, I now get all name entries first,
sort them, and use for bsearching.

This makes scaning Voto Serif GX twice slower though, since we are
creating and sorting the list for each instance. In the next commit,
I'll share this list across different instances to fix this.
We were comparing the passed in key with the ready-to-insert key
rather than the key in the hashtable, so if you ever had a hash
conflicts we'll never insert the new item.

Fontconfig symbols were hardcoded to be either hidden or exported. This patch
adds configurable symbol visibility. This is useful for projects that want to
do in-tree fontconfig builds and not export any symbols, otherwise they would
conflict with the system library's symbols
Chromium is a project that does in-tree fontconfig builds, and the workaround
currently used is "#define visibility(x) // nothing" [1] and building with
"-fvisibility=hidden".
