This adds a cmake module, FindABIMap, which looks for abimap and provides functions to generate a symbol version linker script. The module can be included using find_package(ABIMap). This also adds the option to compile with symbol versioning. The symbol list is obtained from the header files by filtering those marked with the LIBSSH_API modifier. Such symbols are used as input to generate the version script used by the linker. The version script is automatically updated as new symbols marked with LIBSSH_API are added to the header files. If any symbol is removed, the build will fail due to break in the ABI. Symbol versioning is enabled by default if abimap has been found. It is disabled in non-UNIX platforms. It can be disabled by passing "-DWITH_SYMBOL_VERSIONING=OFF" option to cmake.
