remove gdb_string.h
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:
git rm common/gdb_string.h
perl -pi -e's/"gdb_string.h"/<string.h>/;' *.[chyl] */*.[chyl]

read. Servicing an event simply means that the procedure PROC will

be called. We have 2 queues, one for file handlers that we listen

ready. The procedure PROC associated with each event is dependant

|
of the event source. In the case of monitored file descriptors, it

is always the same (handle_file_event). Its duty is to invoke the
|
|
|
|

handler associated with the file descriptor whose state change
|
|
|
|
|
|
generated the event, plus doing other cleanups and such. In the

case of async signal handlers, it is
