Convert systemd-cryptsetup, systemd-cryptenroll, systemd-veritysetup
and systemd-integritysetup to go through the existing dlopen wrapper
for libcryptsetup instead of linking the library directly. Each binary
calls dlopen_cryptsetup() at the start of its run() and uses the sym_*
variants for every libcryptsetup entry point.
Extend cryptsetup-util.{h,c} to cover the libcryptsetup symbols that
these binaries use and that the wrapper was missing:
crypt_activate_by_token_pin, crypt_deactivate, crypt_init_data_device,
crypt_keyslot_status, crypt_set_keyring_to_link (conditional on
HAVE_CRYPT_SET_KEYRING_TO_LINK), crypt_status and
crypt_token_external_path.
With no direct callers of crypt_free() left, drop the non-sym
crypt_freep cleanup variant and rename sym_crypt_freep back to
crypt_freep via DEFINE_TRIVIAL_CLEANUP_FUNC_FULL_RENAME, matching the
naming convention used by other dlopen wrappers (acl_freep,
xkb_context_unrefp, ...). Update the remaining users in src/shared,
src/repart, src/home and src/growfs to the new name.
The four affected meson targets switch from libcryptsetup to
libcryptsetup_cflags so they no longer record a DT_NEEDED entry for
libcryptsetup.so.12.
