Add created symlinks to the exclude file.  This will both make them
less distracting and hide them from the srctree_hash_files function.

The buildclean task should call the package build system clean
command, just implemented for Make for now.

This is meant for recipes where S == B, but can be useful as a
standalone task for other recipes too.

When S == B, set it to run before do_clean which will do what most
developers expect when calling bitbake -c clean.  For S != B, do not
add it before clean as it is not needed and may take some time.

Only the last stamp file should be kept, but unless STAMPCLEAN matches
files generated using STAMP old stamp files may linger.  This may
cause false positives for skipping tasks.

getVarFlag() now defaults to expanding by default, thus remove the
True option from getVarFlag() calls with a regex search and
replace.

Search made with the following regex:
getVarFlag ?\(( ?[^,()]*, ?[^,()]*), True\)

If the user modifies files such as CMakeLists.txt in the case of cmake,
we want do_configure to re-run so that those changes can take effect. In
order to accomplish that, have a variable CONFIGURE_FILES which
specifies a list of files that will be put into do_configure's checksum
(either full paths, or just filenames which will be searched for in the
entire source tree). CONFIGURE_FILES then just needs to be set
appropriately depending on what do_configure is doing; for now I've set
this for autotools and cmake which are the most common cases.

Fixes [YOCTO #7617].

To make sure changes to any source files are detected when externalsrc
is used, it sets BB_DONT_CACHE to force the recipe to be reparsed
every time. Previously, this was done conditionally based on whether
EXTERNALSRC was set. This worked fine for building the base recipe.
But if one tried to build, e.g., a native version of it (provided via
BBCLASSEXTEND), the recipe would not be reparsed as expected.

To solve the above problem, BB_DONT_CACHE is now set for the base
recipe if EXTERNALSRC is set for it or any of it derivatives.

In python3, strings are unicode by default. We need to encode/decode
from command pipelines and other places where we interface with the
real world using the correct locales. This patch updates various
call sites to use the correct encoding/decodings.

Use a unique tempfile as the temporary git index file when determining
the git hash of the source tree. A fixed filename was obviously causing
races (with the git index.lock file) under oe-selftest where multiple
bitbake instances were run against the same source tree at the same
time.
