you were not able to disable the header checks, so if the header was not
there it indicated that you could turn it of. However, the option check
was in the has_header if not outside of it. Further more, header checks
are done in the subdirectory that is done for header checks,
unneccessary cpu_**** flags are removed, global optimization options are
added to the global_arguments instead of just the package_c_args, which
leads to the fact that also all binaries etc. are build by default with
those optimization flags.
This also reduces the amount of options to a minimum of 1 option, to
just control if there should be the optimization or not.
This also changes from host_maschine to target_mschine, since we
probebly want to enable the optimization for the target maschine, not
the host.

for bindings we needed a system that could be used to find all special
directories of every subsystem, for eo files headers etc.
The mechanism is documented in the root meson.build

This uses the meson/ninja depfile functionality + eolian to make
sure proper dependencies between generated files and .eo files
are managed, to ensure consistent re-generation of all generated
files that are affected upon .eo file modification.
For custom rules with multiple outputs, Ninja currently does not
support depfiles. Therefore, split those into two custom rules
so that the depfiles functionality can be enabled. While this
is ugly and slows down the process a little by having to invoke
Eolian twice instead of once, it has to be done and it's still
better than what we had in Autotools anyway.

Fixes T6700.
a new shiny buildtool that currently completes in the total of ~ 4 min..
1 min. conf time
2:30 min. build time
Where autotools takes:
1:50 min. conf time
3:40 min. build time.
meson was taken because it went quite good for enlightenment, and is a traction gaining system that is also used by other mayor projects. Additionally, the DSL that is defined my meson makes the configuration of the builds a lot easier to read.
Further informations can be gathered from the README.meson
Right now, bindings & windows support are missing.
It is highly recommented to use meson 0.48 due to optimizations in meson
that reduced the time the meson call would need.
