a1bb132a81 utils/checkpackagelib/lib_mk.py: handle 'else' and 'elif' statements
An 'else' or 'elif' clause inside a make conditional should not be indented
in the same way as the if/endif clause. check-package did not recognize the
else statement and expected an indentation.

For example:

ifdef FOOBAR
	interesting
else
	more interesting
endif

would, according to check-package, need to become:

ifdef FOOBAR
	interesting
	else
	more interesting
endif

Treat 'else' and 'elif' the same as if-like keywords in the Indent test, but
take into account that 'else' is also valid shell, so we need to correctly
handle line continuation to prevent complaining about the 'else' in:

ifdef FOOBAR
	if true; \
	    ... \
	else \
	    ... \
	fi
endif

We don't add the 'else' and 'elif' statements to start_conditional, because
it would cause incorrect nesting counting in class OverriddenVariable.

76772cefd8 utils/check-package: ignore ACLOCAL_PATH
The aclocal program is provided by the automake package, so it makes
sense to define aclocal-related variables in automake.mk.

Add an exception to check-package to ignore that variable.

1842bb1470 check-package: fix check of file in current dir with -b
One of the possible usages of check-package is to first cd to the
directory that contains the files to test (e.g. a package directory) and
then call the script passing the files in the current dir.
It already works when used for intree files, but for files in a
br2-external it throws an exception because some check functions (from
utils/checkpackagelib/lib_*.py) do need the name of the file being
processed and assume there will be a slash before the name.

Fix all check functions that assume that the full filename being checked
contains a slash. Do not use regexps to extract the filename, use
os.path functions instead.

Notice RemoveDefaultPackageSourceVariable and TypoInPackageVariable lead
to an exception in this case, but ApplyOrder instead generates a false
warning.

Fixes bug #11271.

b03fa5d96f utils/check-package: warn about overridden variables
For the general case, appending values to variables is OK and also a
good practice, like this:
|PACKAGE_VAR = value1
|ifeq ...
|PACKAGE_VAR += value2

or this, when the above is not possible:
|PACKAGE_VAR = value1
|ifeq ...
|PACKAGE_VAR := $(PACKAGE_VAR), value2

But this override is an error:
|PACKAGE_VAR = value1
|PACKAGE_VAR = value2

as well this one:
|ifeq ...
|PACKAGE_VAR += value1
|endif
|PACKAGE_VAR = value2

And this override is error-prone:
|PACKAGE_VAR = value1
|ifeq ...
|PACKAGE_VAR = value2

Create a check function to warn about overridden variables.

Some variables are likely to have a default value that gets overridden
in a conditional, so ignore them. The name of such variables end in
_ARCH, _CPU, _SITE, _SOURCE or _VERSION.

After ignoring these variable names, there are a few exceptions to this
rule in the tree. For them use the comment that disables the check.

02b165dc71 check-package: fix Python3 support
This script currently uses "/usr/bin/env python" as shebang but it does
not really support Python3. Instead of limiting the script to Python2,
fix it to support both versions.

So change all imports to absolute imports because Python3 follows PEP328
and dropped implicit relative imports.

In order to avoid errors when decoding files with the default 'utf-8'
codec, use errors="surrogateescape" when opening files, the docs for
open() states: "This is useful for processing files in an unknown
encoding.". This argument is not compatible with Python2 open() so
import 'six' to use it only when running in Python3.
As a consequence the file handler becomes explicit, so use it to close()
the file after it got processed.

This "surrogateescape" is a simple alternative to the complete solution
of opening files with "rb" and changing all functions in the lib*.py
files to use bytes objects instead of strings. The only case we can have
non-ascii/non-utf-8 files being checked by the script are for patch
files when the upstream file to be patched is not ascii or utf-8. There
is currently one case in the tree:
package/urg/0002-urg-gcc6-fix-narrowing-conversion.patch.

0c83673638 check-package: enable for fs/
The filesystem types can benefit from this script to prevent common
mistakes when submitting patches.

In order to accomplish this:
Do not ignore anymore files from the fs/ directory.
Ignore fs/common.mk as it declares a package infra and not a package itself.
Register the ROOTFS_ as a valid prefix for variables.
Ignore these symbols:
 - PACKAGES_PERMISSIONS_TABLE: defined either by packages through
   pkg-generic or by filesystem types, used by fs/common.mk;
 - SUMTOOL: defined by package mtd, used by filesystem jffs2;
 - TARGETS_ROOTFS: defined by filesystem types, used in the main
   Makefile.

Keep using loose checks that warn about common mistakes while keep the
code simple.
As a consequence the check functions do not differentiate between
packages and filesystems so the symbol PACKAGE_UBI would not generate a
warning for the ubi filesystem neither the symbol ROOTFS_MTD would
generate a warning for the mtd package. But those kind of mistakes are
not common and are obvious in the code review, unlike typos i.e.
ROOTFS_UBl or PACKAGE_MID that would be hard to see in the code review.

29d9f2f014 check-package: avoid false warning of useless flag
Just AUTORECONF = NO is redundant.
Just HOST_AUTORECONF = NO is redundant.
But the combination of AUTORECONF = YES + HOST_AUTORECONF = NO is valid.

So basically for all variables that have inheritance between target and
host, having the host variant of the variable set the variable value
back to its default is correct if the target variable is set.

Instead of increasing complexity of the script to fully detect this
case, ignore the host flag set to its default value as it can be
overriding a non-default value inherited from the equivalent target
flag.

7ca9fc3170 tools: rename to 'utils'
After some discussion, we found out that "tools" has the four first
letters identical to the "toolchain" subfolder, which makes it a bit
unpractical with tab-completion. So, this commit renames "tools" to
"utils", which is more tab-completion-friendly.

This has been discussed with Arnout and Yann.
