This is needed to download tools, but we may not need to do this. At
present binman fails to start if HOME is not set.
Use the current directory as a default to avoid this.

The binary is looked on the system by the suffix of the packer class.
This means binman was looking for btool_gzip on the system and not gzip.
Since a btool can have its btool_ prefix missing but its module and
binary presence on the system appropriately found, there's no need to
actually keep this prefix after listing all possible btools, so let's
remove it.
This fixes gzip btool by letting Bintool.find_bintool_class handle the
missing prefix and still return the correct class which is then init
with gzip name instead of btool_gzip.
Additionally, there was an issue with the cached module global variable.
The variable only stores the module and not the associated class name
when calling find_bintool_class.
This means that when caching the module on the first call to
find_bintool_class, class_name would be set to Bintoolbtool_gzip but the
module_name gzip only, adding the module in the gzip key in the module
dictionary. When hitting the cache on next calls, the gzip key would be
found, so its value (the module) is used. However the default class_name
(Bintoolgzip) is used, failing the getattr call.
Instead, let's enforce the same class name: Bintool<packer>, whatever
the filename it is contained in.

A binary download is not great, since it depends on libraries being
present in the system. Build futility from source instead.

The code to check the version is very similar between binaries, the most
likely only needed variables are the regex to find the version (already
supported) and the args to pass to the binary so that it prints this
version (e.g. --version, -V or similar).
Let's make it a parameter of Bintool so that code duplication can be
avoided for simple changes.

Version checking has nothing specific to compression/decompression tools
so let's move it to the Bintool class.

Add gzip bintool to binman to support on-the-fly compression of Linux

Each bintool has some documentation which can be useful for the user.
Add a new command that collects this and writes it into a .rst file.

Binman requires various tools to actually work, such as 'lz4' to compress
data and 'futility' to sign Chrome OS firmware. At present these are
handled in an ad-hoc manner and there is no easy way to find out what
tools are needd to build an image, nor where to obtain them.
Add an implementation of 'bintool', a base class which implements this
functionality. When a bintool is required, it can be requested from this
module, then executed. When the tool is missing, it can provide a way to
obtain it.
Note that this uses Command directly, not the tools.Run() function. This
allows proper handling of missing tools and avoids needing to catch and
re-raise exceptions.
