[PATCH] secnet.h: Change bool_t to a C99 _Bool

[Ian Jackson]

This will (a) stop misleading readers of the code (b) make it possible
to write code expecting an implicit !! to be applied to assignments to
booleans (c) possibly make secnet smaller or faster.

I don't expect this to produce any functional change, but I haven't
reviewed every bool_t in secnet to check.
