The external gettext library should be used on main libcryptsetup,
not later for programs (these do not call any translations).
(Also it was in the wrong order there failing compilation.)
Starting with GCC10 and LTO enabled, current symbols
versioning hack does not work anymore. This patch
reflects on that and should be compatible with older
compilers that does not support __attribute__((symver))
yet.
Inspired by following code:
https://github.com/linux-rdma/rdma-core/blob/master/util/symver.h
To avoid confusion, use just one lib include and specify sub-directories
for format inclusions.
This should also help some analysis tools to find proper includes.
Introducing new library supposed to be used in
cryptsetup tools and future cryptsetup loadable plugins
TODO:
- distribution
- cleanup header files
- incorporate also plugin API?
