Fix#119
when parallel build is enable, multiple dpkg-buildpackage
instances are running at the same time. /var/lib/dpkg is shared
by all instances and the /var/lib/dpkg/updates could be corrupted
and cause the build failure.
the fix is to use overlay fs to mount separate /var/lib/dpkg
for each dpkg-buildpackage instance so that they are not affecting
each other.

This pull request was cherry picked from "#1238" to resolve the conflicts.
- Why I did it
Add support to specify source address for TACACS+
- How I did it
Add patches for libpam-tacplus and libnss-tacplus. The patches parse the new option 'src_ip' and store the converted addrinfo. Then the addrinfo is used for TACACS+ connection.
Add a attribute 'src_ip' for table "TACPLUS|global" in configDB
Add some code to adapt to the attribute 'src_ip'.
- How to verify it
Config command for source address PR in sonic-utilities
config tacacs src_ip <ip_address>
- Description for the changelog
Add patches to specify source address for the TACACS+ outgoing packets.

- Add .gitignore files in each subdirectory of src/, so as to reduce the size of the .gitignore file in the project root, and also make it easier to maintain (i.e., if a directory in src/ is removed, there will not be outdated entries in the root .gitignore file.
- Also add missing .gitignore entries and remove outdated entries and duplicates.

* Switch the nss look up order as "compat" followed by "tacplus".
This helps use the legacy passwd file for user info and go to tacacs only if not found.
This means, we never contact tacacs for local users like "admin".
This isolates local users from any issues with tacacs servers.
W/o this fix, the sudo commands by local users could take <count of servers> * <tacacs timeout> seconds, if the tacacs servers are unreachable.
* Skip tacacs server access for local non-tacacs users.
Revert the order of 'compat tacplus' to original 'tacplus compat' as tacplus
access is required for all tacacs users, who also get created locally.
* [TACACS+]: Add support for TACACS+ Authentication

* [TACACS+]: Fix nss-tacplus filter some valid TACACS+ username
* The NAME_REGEX for username check in plugin nss-tacplus is
the ANSI version "^[0-9a-zA-Z_-\ ]*$", but the regular expression
in /etc/adduser.conf is not defined as ANSI version. To avoid
nss-tacplus filter some valid TACACS+ username, remove username
check.
