Some ".c" files define *_PRIVATE macros, but those macros are
not used in any header file. Delete them.
These changes were created using the "make autostyle" from
32522, and then split into commits.
Fake circuits are created everywhere in the unit tests. This is an attempt at
centralizing a "fake circuit creation" API like fakechans.c does for channel.
This commit introduces fakecircs.c and changes test_relay.c and
test_circpadding.c which were using roughly the same code.
This will allow easier OR circuit creation for the future tests in
test_circuitmux.c
