Michael Frysinger a91ef48390 sim: export cb_get_string for people to use
The common sim code provides a useful "get_string" function which reads
a C string out of the target's memory space.  So rename and export it
for other people to use.

_STRACE_INTERFACE_ACTIVATE_ADDR which informs whether this is a forked process

strace.attached().

it's a cygwin process.  Accommodate change to write_child argument list.

rather than as C statements and make sure that flags is set to zero initially.
* spawn.cc (child_info_spawn::worker): Use iscygwin() test for determining when

(PROC_DETACHED_CHILD): Delete.
* spawn.cc (chExeced): Delete.
(child_info_spawn::worker): Rename from spawn_guts.  Use elements of
