This commit adds a new section
Working with Buildroot
-> Details in configuration
-> Cross-compilation toolchain
that gives a lot of details about our three toolchain backends. It
takes some elements that were previously later in the manual in
"Embedded basics" and in "External toolchain" and combines them with
more details about internal backend and Crosstool-NG backend.
The "Embedded basics" section becomes empty and is therefore
removed. A few elements have been lost in the process, but they were
considered to not be really useful, especially located so far in the
manual.

As discussed with Samuel Martin, there are a few questions about some
Buildroot configuration aspects that come very often on the IRC
channel and on the mailing-list. Topics such as the /dev management
and init systems are often raised.
Therefore, this patch adds a new section that provides details about
the Buildroot configuration possibilities. It does not aim at
replacing the help text of each configuration option, but rather to
complement them by providing more background. Having those
informations in the manual will also make it easier for us to point
newcomers to the right place in the documentation when they have
questions.
Note that this section will replace the "Embedded basics" section that
comes way too late in the manual. This is done in a followup commit.

The depends-on-vs-select part of the manual really deserves its own
section title (especially because it is referred to and the xref gets
a 'sinpara' in PDF if the section doesn't have a title). So restructure
the surrounding sections to reduce the section nesting depth.

The tutorial for autotools-package and cmake-package currently gives
the bad example of setting _INSTALL_TARGET to YES, which is the default.
So change this into an example with _INSTALL_TARGET = NO, and explain in
which case this is relevant.

Consider the second chapter: "starting-up", as a tutorial.
Assuming that, using.txt only contains the very first commands used to get
configure and build its very first target system.
So, the following subsection from using.txt have been to common-usage.txt:
- Offline builds
- Building out-of-tree
- Environment variables

The new skeleton of the manual as it has been thought:
1. About Buildroot:
Presentation of Buildroot
2. Starting up:
Everything to quickly and easily start working with Buildroot
3. Working with Buildroot
Basics to make your work fitting your needs
4. Troubleshooting
5. Going further in Buildroot's innards
Explaination of how buildroot is organised, how it works, etc
6. Developer Guidelines
7. Getting involved
8. Contibuting to Buildroot
9. Legal notice
10. Appendix
It is easy to distinguish two parts in this plan:
- Sections 1 to 4 mainly address people starting with Buildroot
- Sections 5 to 10 are more focused on how to develop Buildroot itself
Most of the existing sections have just been moved in the hierarchy,
few were split and dispatch in, what i think was the relevant section,
and numerous others have been created.

This directory groups the following elements:
* the default root filesystem skeleton
* the default device tables
* the Config.in options for system configuration (UART port for
getty, system hostname, etc.)
* the make rules to apply the system configuration options
Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.
As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.

With the introduction of a specific macro for host targets, it was decided
to also make the names of the macros more intuitive: generic-package,
autotools-package and cmake-package.

Create host-generic-package, host-autotools-package and
host-cmake-package macros. Such a macro is more intuitive to use than
the $(call ...,host) construct. Also it speeds things up by having
one less $(call ...) evaluation.
Also includes documentation update, but not for buildroot.html.
This brings the time for 'make -qp' (which is used by bash-completion)
down from 1.85s to 1.35s on my laptop.

The current structure of the LIBFOO_SITE_METHOD paragraph would make
it difficult to add documentation for the "file" and "local" methods.
There are enough possible values for LIBFOO_SITE_METHOD that
describing them in a sub-list seems to work well, which makes it
easier to add documentation for new methods.

This modifies the definition of DOWNLOAD to receive two arguments:
the first one is the full URL of the file to download, whereas the second
(and optional) is the name the file will have once downloaded.
Same thing with the SOURCE_CHECK_WGET and SCP functions.
All calls to these functions have been changed to the shortest form of
the new API, except for toolchains acquisition. Since there is quite a
number of different toolchains this call to DOWNLOAD is better set to the
generic one.
