Use meson as the main build system (#365)

* Build: Add an iscsiuio 'build_date.sh' script

This is currently unused, but will be used by meson to
build the "build_date.[ch]" files used by iscsiuio.

* Build: have git ignore file '.setup'

I commonly use this file for shell aliases/functions.

* Add framework to support building using meson.

This adds the ability to use meson/ninja to build open-iscsi
and iscsiuio, rather than the current system that uses 'autoconf'
for iscsiuio and uses 'make' for everything else.

The old make/autoconf system is left in place, for now, but
deprecated, including a warning about that when running 'make all'
or 'make user' from the top-level.

* utils/build: enhance iscsi-iname to generate prefix

Added new "-g/--generate-iname-prefix" argument to generate the
InitiatorName= prefix. Also, updated iscsi-iname to use getopts.
Also, use the new option from meson.

* git/meson: remove 'builddir' from ignored files

The build directory can be called anything.

Suggested by: Eli Schwartz

* iscsiuio build: fix new build_date.sh script

Fixed several issues:

- fix option handling for "-S"
- fix epoch date handling from env (noticed by Eli Schwartz)
- remove debug statements

* iscsiuio meson: warn when not creating a symlink for iscsiuio

* meson: install man pages more efficiently

We don't need to specify path or subdirectory

* iscsiuio meson: remove unused source date epoch option

This option was never used, since we pass this info
from the environment.

* meson: no need to set libdir: default is fine

* iscsiuio meson: no need to add c_args: already there

* Don't generate initiatorname when cross-building (#367)

Let it be generated by the iscsi-init service.
