This is a follow-up patch to 6f7835f309b9.
As explained previously, when running from an IDE, it can happen that
the IDE imports some lldb scripts by itself. If the user also tries to
import these commands, lldb will show the following message:
```
error: cannot add command: user command exists and force replace not set
```
This message is confusing to the user, because it suggests that the
command import failed and that the execution should stop. However, in
this case, lldb will continue the execution with the command added
previously by the user.
To prevent that, this patch updates every first-party lldb-packaged
custom commands to override commands that were pre-imported in lldb.

This is a combination stand alone BSD archive tool that can dump BSD archives:
% bsd.py /path/to/foo.a
Search archives for an object file:
% bsd.py --object foo.o bar.a
Dump the symbol definitions found in the __.SYMDEF objects:
% bsd.py --symdef bar.a
Find symbols by name that are listed in the __.SYMDEF objects:
% bsd.py --symbol _Z123 bar.a
Extract objects from BSD archives:
% bsd.py --object foo.o bar.a --extract
% bsd.py --object foo.o bar.a --extract --outfile /tmp/foo.o
% bsd.py --object foo.o bar.a --extract --mtime 0x1234556
It also has installs a new LLDB command line command when imported into LLDB:
(lldb) command script import ~/Dropbox/bin/bsd.py
The "verify-debug-map-objects" command has been installed, type "help verify-debug-map-objects" for detailed help.
(lldb) verify-debug-map-objects a.out
This will iterate through all object files and verify the modification times match for any .o files, it will verify any .o files from BSD archives are found and have matching modification times and print out errors if any are found.
