f459985261 Add imctrl and imkey options, inspired by cannactrl and fepkey options in 
nvi-m17n by itojun.

If imctrl option is set, input method is controlled by using escape
sequences compatible to Tera Term and RLogin. The state of input method in
commands specified by imkey option is saved and restored automatically.
Input method is then deactivated on returning to command mode.

b3019d4b3d Correct previous change to CHAR_T_OFFSET 
The intended operation is offsetof(), not alignof().

4e2759a682 Do not cause Undefined Behavior in vi(1) 
Replace unportable manual calculation of alignof() that causes UB, with
a GCC extension __alignof__.

This fixes a problem reported by UBSan with the MKSANITIZER distribution.

65b076fb4d Make sure that every wide char occupies at least one display width: 
- Replace non-printable multibyte char with ?-symbol.
  - Put space before non-spacing char.

Fix problems reported in PR bin/53164 and
PR bin/53323, that are because we did not take into account non-printable
multibyte char of wctob(wc) == EOF && wcwidth(wc) == -1.

bf7113376a Create a new bsd.hostinit.mk file and put the build definitions for all host 
programs there; make all Makefiles that use bsd.hostprog.mk include it.
Namely turn off MKREPRO and don't make lint, man pages, info files etc.
Remove the Makefile.inc files that contained these same settings, and
remove the settings from Makefile.host

b9c2640a34 fix GCC 6.4 issues (finally a couple that aren't actual bugs, 
but only weird code?):

amd's amfs_program_exec() has a missing {} issue.

flex's check_options() has odd inconsistent identation that
trips the new ident checker.

ntpd's oncore_check_leap_sec() and oncore_set_traim() have
missing {} issues.

sntp's optionLoadNested() an identation weirdness that
trips the new ident checker.

vi's cl_attr() has a wrong {} issue, and its vs_paint() has
an identation weirdness that trips the new ident checker.

76fae9132e When testing to see if a signal handler was previously installed in 
h_winch, test sa_handler against all SIG_* actions defined in sys/signal.h
instead of just 0. Corrects an issue where vi crashes after a window is
resized.

66231ee6b4 - Add -Wno-unused and -Wno-unsequenced for gcc and clang, respectively. 
This is because encoding conversion macros yield such like:

    #define FILE2INT5(sp,buf,n,nlen,w,wlen) (w = n, wlen = nlen, 0)

- Silence gcc warnings on nonliteral arguments for snprintf(3) in v_increment.c,
  that are overlooked for swprintf(3) in the case of USE_WIDECHAR == "yes".
