Keep only existing exports, the commented out functions have been hidden
in 56e9963474 ("btrfs-progs: libbtrfs: hide unused symbols, same
version") in 5.14 and no problems have been reported.

Another step to decommission libbtrfs in favor of libbtrfsutil. Remove
all symbols that are not used by snapper, as this is the only known
widely distributed tool that uses some of the librarized functionality,
apart from the ioctls.
The symbol versioning does not allow to remove once exported symbol so
this is a dirty trick that works only in this situation. The unused
symbols are not exported anymore BUT the library has the same version.
This would be normally an ABI violation, but there's no change for
snapper (build and runtime verified on version 0.9.0).
The known used symbols are preserved.

libbtrfs isn't a proper library and exports internal headers that aren't
included from other headers and their use in public API does not make
sense. There are no known applications using them so don't install them.

The shared library exports many functions that are not supposed to be
public, like rb-tree, crc32c or internal helpers but as this has been
potentially in use we should at least make a list. There's only a
subset being used by the snapper project.
Export majority of current symbols visible in libbtrfs so any future
additions to libbtrfs objects are automatically hidden and don't pollute
the namespace further.
Note that all projects should switch to libbtrfsutil rather than
libbtrfs that exists for historical reasons and will be deprecated in
the future.
