34106f4a1a include: Allow git kernel branch selection
This allows the selection of a specific branch in the menuconfig
when using a kernel downloaded from GIT.

c77feae6be include: Clean-up kernel git command options management
The way git options are managed in kernel-defaults.mk makes additions

difficult. If requires different code path for each option; it's
ok so far as we handle only one option, but if we want to make the git
clone mechanism more flexible, more option will be required, which
will become tedious.

So; we'll move the GIT options into a variable, that may or may not be
set depending on the configuration, and we'll pass this variable to the
git command.

45e3540a3f config: Remove KERNEL_GIT_LOCAL_REPOSITORY option
The GIT_LOCAL_REPOSITORY option adds the --reference argument to the
git clone kernel command line, if KERNEL_GIT_CLONE_URI is set.

This option is intended to speed-up the repo creation by using local
objets rather than downloading it. However, a local repo can be cloned
much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree.

In that case, git clone will bypass the normal "git aware" transport
mechanism and clone the repository by copying and hardlinking objects
rather than downloading it, resulting in a significant speed increase.

That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just
remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.

76133009c9 sparse: add as a new package selectable from the config
This change does multiple things, all related to enable sparse usage as
a static analysis tool selectable from the OpenWrt configuration:
*add a KERNEL_SPARSE option in the config to add sparse to the kernel
 build (through the C=1 option usage)
*add sparse as a new host tools. It will get selected automatically when
 the above option will be enabled

34ffb526a2 build: rework verbosity level selection
V=99 and V=1 are now deprecated in favor of a new verbosity class system,
though the old flags are still supported.
You can set the V variable on the command line (or OPENWRT_VERBOSE in the
environment) to one or more of the following characters:

- s: stdout+stderr (equal to the old V=99)
- c: commands (for build systems that suppress commands by default, e.g. kbuild)
- w: warnings/errors only (equal to the old V=1)
