[patch 0/4] [RFC] tools cleanup v1

[Michal H. <ms...@gm...>]

Hi,
this short patch series cleans up our tools which are located in
src/tests/tools directory. We want to expose those tools to user and this
requires two things:
	- incorporate them into our building infrastructure (configure,
	  make, ...)
	- expose them to the src directory because src/tests is for internal
	  usage only.

Short summary of each patch:
- [Patch 1/4] configure: Add enable-tools option.
	- new configure option --enable-tools
	- adds boost-program-options detection
	- updates Makefile.flags.in to export those values
- [Patch 2/4] tools: move tools to src and honor --enable-tools configuration options.
	- move tools to src/tools
- [Patch 3/4] tools: fix parse_object building
	- compile fix for parse_object
- [Patch 4/4] tools: pagemetrics 64b compilation fix
	- compile fix for pagemetrics

Martin, could you have a look at patches?
I have tested them on Debian 32b, OpenSuse (32b and 64b) and Gentoo (64b).
OpenSuse 64b requires --with-boost=/usr/lib64 additional parameter which is
necessary because libraries are not checked in that target - very same
as used to be with boost-iostreams (it is documented in README). Gentoo 64b
uses /usr/lib - so no parameter required.

Note that tools are not included in any installation targets which is intentional
because they are not intended for system wide installation at this stage.

Thanks
