[PATCH v2 1/3] Make gdb_load_shlibs return the destination path of the library


This patch makes gdb_load_shlibs return the destination path of the
copied library.  To make the procedure implementation and interface more
straightforward, it also changes it so that it accepts a single shared
library path at the time.  Therefore, calls that are passed multiple
libraries:

  gdb_load_shlibs $lib1 $lib2

must be changed to separate calls:

  gdb_load_shlibs $lib1
  gdb_load_shlibs $lib2

A subtle impact is the solib-search-path handling.  In the former
version, solib-search-path is set using the directory of the first
passed lib (further calls overwrite the value).  In the later version,
the directory of the library passed to the last call to gdb_load_shlibs
remnains.  I don't think that's a problem in practice, since if we had
tests that needed multiple different paths in solib-search-path, they
wouldn't work in the first place.

Changed in v2:

	* Split behavioural and rename changes in two separate patches.

gdb/testsuite/ChangeLog:

	* lib/gdb.exp (gdb_load_shlibs):  Accept a single argument.  Return
	result of gdb_remote_download.
	* gdb.base/ctxobj.exp: Split gdb_load_shlibs call.
	* gdb.base/dso2dso.exp: Likewise.
	* gdb.base/global-var-nested-by-dso.exp: Likewise.
	* gdb.base/print-file-var.exp: Likewise.
	* gdb.base/shlib-call.exp: Likewise.
	* gdb.base/shreloc.exp: Likewise.
	* gdb.base/solib-overlap.exp: Likewise.
	* gdb.base/solib-weak.exp (do_test): Likewise.
	* gdb.base/unload.exp: Likewise.
