Renaming c_true to tnil.

Macros called c_* should produce C counterparts of
Lisp val objects, like c_num and c_str.

* lib.h (c_true): Renamed to tnil.

* eval.c (lexical_var_p, lexical_fun_p): c_true to tnil.

* lib.c (less, chr_isalnum, chr_isalnum, chr_isalpha,
chr_isascii, chr_iscntrl, chr_isdigit, chr_isgraph,
chr_islower, chr_isprint, chr_ispunct, chr_isspace,
chr_isblank, chr_isunisp, chr_isupper, chr_isxdigit,
chr_toupper, keywordp): Likewise.

* stream.c (catenated_stream_p): Likewise.

* sysif.c (wifexited, wifsignaled, wcoredump, wifstopped,
wifcontinued): Likewise.
