Simplify expand_tcbtab and alloc_tcb
Get rid of a few intermediate variables, simplifies a few expressions,
and uses error_msg_and_die instead of more verbose
fprintf+cleanup+exit sequence.
In alloc_tcp, I use memset to clear entire new tcp.
This not only saves a few bytes of code, but lowers the chances
of future bugs where some data "leaks out" into new tcb's
from old ones because we forgot to re-initialize it.
* strace.c (expand_tcbtab): Simplify this function. No logic changes.
(alloc_tcb): Likewise.
