[#36737359]
The merging of reload_module and the various load_module methods
resulted in the module loading from disk, but because the Hash entry in
the module manager was not deleted before on_module_load was called, the
newly reloaded module was logged as an ambiguous module name instead of
a reload. In order to report the reload errors correctly, I determined
that module_load_error_by_reference_name should really be
module_load_error_by_path. I eliminated faild in favor of this new name
since failed was just calling the attribute and the attribute's name is
clearer about the format of the data.
Tested by run rexploit and then exiting over and over with
ms08_067_netapi. When I messed up the file so it couldn't load, by
adding `inclde Exploit` (note mispelling of `include`), it reported the
error to msfconsole. When I removed the bad line and added a puts
"RELOADING <n>", where I kept incrementing n and saving the file, the
new number appeared during each rexploit.
[#36737359]
Write the module_eval backtrace to the log, but only the error's class
and name to Msf::ModuleManager#module_load_error_by_reference_name as
the contents of the Hash are printed in the console, which should never
recieve backtraces.
[#36737359]
Refactor the behavior of loading symbolic modules from cache by renaming
methods so it's clearer what they do and ensure that cached modules from
Fastlibs and directories can both be loaded, which was not previously
possible since the demand_load_module only called load_module_from_file.
[Fixes#36737359]
Refactor Msf::ModuleManager into concerns so its easier to understand and
duplicate code can be made DRY. The refactoring also ensures that when
loading from directories, Fastlibs, or reloading, the wrapper module will
always be named so that activesupport/dependencies will function.
