Remove cleanup from remote.c
This removes the remaining cleanup from remote.c, by changing
remote_state::buf to be a gdb::char_vector, and then fixing up all the
fallout. The resulting patch is somewhat ugly, but on the other hand,
it eliminates some possibilities for mistakes.
Regression tested using the
Fedora-x86_64-native-extended-gdbserver-m64 builder on the buildbot.
gdb/ChangeLog
2019-01-15 Tom Tromey <tom@tromey.com>
* remote.c (class remote_state) <buf>: Now a char_vector.
<buf_size>: Remove.
(remote_target::getpkt): Change type of buf. Remove sizeof_buf
parameter.
(remote_target::getpkt_or_notif_sane_1)
(remote_target::getpkt_sane)
(remote_target::getpkt_or_notif_sane): Likewise.
(class remote_target) <putpkt>: New overload.
(remote_target::read_frame): Change type of "buf_p". Remove
sizeof_p parameter.
(packet_ok): New overload.
(packet_check_result): New overload.
Update all uses.
