compat: fix glaringly broken init-time handling.
We are doing numerous compat_ver checks in various init
functions, to enact alternative symbol registrations. Only
problem is, compat_ver is always zero during initialization;
it is not set until the -C option is processed in txr_main.
Registrations must be fixed up after initialization;
that's what the compat_fixup mechanism is for.
This is an long-standing problem which affects compatibility
operation going back over 150 versions.
* arith.c (arith_init): Move compat logic to
arith_compat_fixup.
(arith_compat_fixup): New function.
* arith.h (arith_compat_fixup): Declared.
* eval.c (eval_init): Move compat logic to eval_compat_fixup.
* ffi.c (ffi_init): Move compat logic to ffi_compat_fixup.
(ffi_compat_fixup): New function.
* ffi.h (ffi_compat_fixup): Declared.
* regex.c (regex_init): Move compat logic to
regex_compat_fixup.
(regex_compat_fixup): New function.
* regex.h (regex_compat_fixup): Declared.
* stream.c (stream_init): Move compat logic to
stream_compat_fixup.
(stream_compat_fixup): New function.
* stream.h (stream_compat_fixup): Declared.
* struct.c (struct_init): Move compat logic to
struct_compat_fixup.
(struct_compat_fixup): New function.
* struct.h (stream_compat_fixup): Declared.
* lib.c (compat_fixup): Call arith_compat_fixup,
ffi_compat_fixup, regex_compat_fixup, stream_compat_fixup and
struct_compat_fixup.
