Just a formal correction for the previous commit. Enclose variables
within {} signs.

Running `thunderbird -g` produces the following error:

    INFO  -> Starting Thunderbird with GDB ...
    INFO  -> LANG= /usr/bin/gdb -ex "handle SIG38 nostop" -ex "handle SIGPIPE nostop" -ex "run" /usr/lib/thunderbird/thunderbird
    /usr/bin/thunderbird: line 254: /usr/bin/gdb -ex "handle SIG38 nostop" -ex "handle SIGPIPE nostop" -ex "run" /usr/lib/thunderbird/thunderbird : No such file or directory

This occurs because exec is passed a single argument, which it
interprets as a file name that does not exist.  Instead, use the
following steps:

1. Build a command string which combines ${TB_GDB_DEFAULT_OPTS} and
   ${TB_ARGS[@]} (using `printf ' %q'`).
2. Print the command string with output_info.
3. Run it using `eval` (for word splitting) and `exec` (to replace the
   shell process with gdb, as before).

There is some fishy upstream with the usage of an external libnss3
library. The configure system for thunderbird requires libnss3-dev
>= 3.51.1, we have 3.61 around but while built we did use 3.67.
This results in malfunctions for SSL/TLS operations as obviously we
would have needed a greater libnnss3 version on the system thunderbird
is running.

Given we are short before the full freeze and the 78 ESR circle is
nearly over, a rebuild thunderbird package which is using the internal
NSS source is fully working we switch the built to use the internal NSS
source.

Rework of the man page as especially the debug call has changed for
while and this wasn't put into modifying thunderbird(1).

The lower case variant "thunderbird" is always used within
StartupWMClass in contrary to the upper case string "Thunderbird" which
is only available in some window managers.
Adjust the setting within the dekstop file so we announce the always
available string.

The application icon is already installed in various sizes in the
global hicolor icon theme; hence, there is no need to provide a symlink
to it also in the legacy pixmaps location.

Doing some prefixing of local variables that using really generic names
otherwise which might conflicht in case they have been set outside of
the context from this script.

The package thunderbird-dbg isn't build anymore, point the usage output
instead to the correct package thunderbird-dbgsym.

If the user who launched thunderbird had exported DEBUG=1 the launcher
didn't launch anything (because DEBUGGER was not set).
