POST module duplicate search results

Running a POST module in meterpreter was causing duplicate search
results for the executed module.  For example, running
post/windows/gather/checkvm would produce duplicate results for that
module when executing “search checkvm” in msf.

Debugging revealed that the cmd_exec function in meterpreter’s ui
command_dispatcher core was creating the specified module, and then
promptly reloading it.  The reload function was causing the duplicate
module_detail record to be written to the msg postgres database
instance.  Further analysis revealed that the “original_mod” could be
used for running the post module, so the “reloaded_mod” was removed
and the “original_mod” used in it’s place to run the post module.

Add admin check to smb_login

The attached updates changes smb_login to detect if the newly discovered user is an administrator.  It is based on code from Brandon McCann "zeknox" submitted in PR #1373, the associated changes, and the newer PR #2656.
The changes should correct a few issues with PR #1373 and #2656 and address Redmine bug #8773.

Specifically it:

 - Fixes the admin detection code by using simple.disconnect(<share>) instead of disconnect()
 - Adds support for detecting if the remote host will allow connects using any domain name when one of the new status codes is returned
 - Dealt with the issue in PR #2656 where the username was prefixed with a '\'


Verification

Be connected to a database
Run this against a machine with a known user and admin user
See that the admin user is reported correctly
See that the non-admin user is reported correctly
Check the output of creds
Select a target that requires a domain in order to authenticate
In the stored credentials, with CHECK_ADMIN enabled, see that the domain name is, in fact, preserved in the reporting

To validate that the remote domain ignores domain value use the following command from a windows system:

net use \\<hostip>\admin$ /user:<random_value>\<username>   <password>

Search Result Uniqueness

SeeRM #8754

Cast the results of the query to an array and perform the uniq
function passing a block which provides uniqueness based
on the return value, which in this instance is ‘fullname’
This was done because the uniq function in AREL cannot take
a specific field for uniqueness, and the sophistication of the query
make grouping nearly impossible.  Initial testing showed negligible
speed difference to the user.

* This refactors the logic of webview_addjavascriptinterface into a mixin (android.rb).
* Additionally, some behavior in pdf.rb had to be modified (in backwards-compatible ways).

Revert change to trailer(). Kill dead method.

* I verified that changes to PDF mixin do not affect any older modules that

running the module and diffing the pdf's generated by each branch. There were
no changes.
