71bc4af6ed Fix potential buffer overflow and undefined behavior.
The buffer allocated in read_chat() could be 1 element too short, if the
chatstr parameter passed in is 1 or 3 charachters long (e.g. "a" or "a b").
The allocation of the pointer array does not account for the terminating
NULL pointer in that case.

Overlapping source and destination strings are undefined in strcpy().
Instead of moving a string to the left by one character just increment the
char pointer before it is assigned to the results array.

50541c922e In libexec/getty/chat.c, replace && with & in chat_send(). The intent
is to test if the CHATDEBUG_SEND bit is set in the chat_debug global.

391a2becf1 Removed unused include of <sys/resource.h> instead of depending on
namespace pollution only 1 layer deep in <sys/stat.h> for its
prerequisite <sys/time.h>

Removed other unused includes.

26015440b9 Tidy-up modem-chat handling: ensure tty modes are restored to
'sane' standard (not raw) settings before abort/exiting; move
responsibility of setting raw mode for chat-handling out of
chat.c to avoid doing redundant tc{s,g}etattr()s; move DE
pause prior setting standard mode before issue/login prompt to
avoid echoing modem connect strings. Fixed up comment styles
in a couple of places.

fe552114a3 Added:
ic=expect/send script    modem init script
    ac=expect/send script    modem answer script
    ct#val		     chat script timeout (seconds)
    rt#val		     recycle timeout (seconds) if 'ac' set
    dc#val		     debug bitmask for debugging chat scripts
    hw	(boolean)	     enable crtscts handshaking
    if=path		     'issue' file sent prior login prompt

chat.c is a simplistic expect/send chat module.
