Merge NetBSD changes, among them:

el.c 1.44, el.h 1.17, editline.3 1.53, histedit.h 1.31:
# add EL_GETFP, and EL_SETFP.

el.c 1.42, term.c 1.46, term.h 1.18, editline.3 1.52, histedit.h 1.29:
# - Add more readline functions, enough for gdb-6.5
# - Make el_get varyadic, and implement EL_GETTC.
# - XXX: the EL_SETTC api will change in the future.

Note: The latter change breaks the ABI of the el_get() function.
