[PATCH 0/9] [gdb/testsuite] Fix remote target test fails

[Tom de Vries <tdevries@suse.de>]

Fix testsuite failures with target board remote-gdbserver-on-localhost.

This is a follow-up on the proposed patch series
https://sourceware.org/pipermail/gdb-patches/2022-October/193147.html by
Ivan Tetyushkin.  I started from scratch, but borrowed from the original
series, so I've marked that by using co-authored-by.

This patch series takes a different approach than the original proposal:
rather than trying to construct absolute file names that will work on the
remote target, make things work with the names as returned by remote_download.

One of the fixes is to add a REMOTE_TARGET_USERNAME parameter to the target
board, such that we can limit file permissions to get a more realistic
emulation of an actual remote target, and this allows us to reproduce the
failures reported by Ivan.

Tested on x86_64-linux, using target board remote-gdbserver-on-localhost.
