bitbake: Remove whitelisted vars from non-task deps
Though the value of variables in the BB_BASEHASH_WHITELIST is kept out of the
checksums, dependency on them is not, at least for variables and non-task
functions. In the code, the whitelist is removed from the overall task dep
list, but not the individual variable deps. The result of this is that
functions like sysroot_stage_all and oe_runmake end up with whitelisted
variables like TERM listed in their dependencies, which means that doing
a 'unset TERM' before building will result in all checksums for tasks that
depend on those changing, and shared state reuse not behaving correctly.
This is only really a potential issue for variables from the environment, as
it's the existance/removal of the variable that's an issue, not its value, and
the other whitelisted variables are set in our metadata. This which means in
practical terms the only cases where this is likely to be an issue are in
environments where one of the following are unset: TERM, LOGNAME, HOME, USER,
PWD, SHELL. This may seem like an unlikely circumstance, but is in fact a real
issue for those of us using autobuilders. Jenkins does not set TERM when
executing shell, which means shared state archives produced by your jenkins
server would not be fully reused by an actual user.
Fixed by removing the whitelisted elements from the individual variable deps,
not just the accumulated result.

bitbake: cache/fetch2/siggen: Ensure we track include history for file checksums
Currently, if you reference a file url, its checksum is included in the
task hash, however if you change to a different file at a different
location, perhaps taking advantage of the FILESPATH functionality, the
system will not reparse the file in question and change its checksum to
match the new file.
To correctly handle this, the system not only needs to know if the
existing file still exists or not, but also check the existance
of every file it would have looked at when computing the original file.
We already do this in the bitbake parsing code for class inclusion. This
change uses the same technique to log the file list we looked at and
if files in these locations exist when they previously did not, to
invalidate and reparse the file.
Since data stored in the cache is flattened text, we have to use a string
form of the data and split on the ":" character which is ugly, but is
an internal detail we can improve later if a better method is found.
The cache version changes to trigger a reparse since the previous
cache data is now incompatible.
