unwind: rename env frames.

Unwind frames of type ENV exist for the sake of the pattern
language. Let's rename them accordingly.

* match.c (tleval, tleval_progn, h_fun, tx_subst_vars, v_bind,
v_output, v_filter, v_fun): Occurrences of the macros
uw_env_begin and uw_env_end are renamed.

* unwind.c (uw_env_stack): Renamed to uw_menv_stack.
(uw_unwind_to_exit_point, uw_abscond_to_exit_point,
uw_find_env, uw_pop_frame, revive_cont): Follow
rename of UW_ENV to UW_MENV and uw_env_stack to uw_menv_stack.
(uw_push_env): Renamed to uw_push_match_env, and updated to
follow renames.

* unwind.h (enum uw_frtype, uw_frtype_t): UW_ENV renamed
to UW_MENV.
(uw_push_env): Renamed to uw_push_match_env.
(uw_env_begin, uw_env_end): Renamed to uw_match_env_begin an
uw_match_env_end.
