* MAINTAINERS: Add myself as dcache.c maintainer.

* remote-nindy.c (nindy_load): Invalidate dcache.

* dcache.c (dcache_invd): Renamed from dcache_flush.  The term
flush with respect to caches usually implies that data will be
written to memory.
(dcache_init, dcache_xfer_memory): Updated.
* monitor.c (flush_monitor_dcache, monitor_resume, monitor_load):
Updated.
* ocd.c (ocd_open, ocd_resume, bdm_reset_command): Updated.
* remote-bug.c (bug_load, bug_resume): Updated.
* remote-nindy.c (nindy_open, nindy_resume): Updated.
* remote-sds.c (sds_open, sds_resume): Updated.
* remote-utils.c (gr_open): Updated.
* remote.c (remote_open_1, remote_resume, remote_async_resume,
remote_cisco_open): Updated.
* wince.c (child_create_inferior, child_resume): Updated.

* monitor.c (monitor_open): Free dcache before creating a new one.
* dcache.c (dcache_free): New function.
* dcache.h (dcache_free): New prototype.
