Isabelle2020 doesn't allow sharing session directories between the document
session and non-document session. Instead of duplicating things, this commit
pulls the document build back into the ASpec session, but changes the build
such that the git revision is read directly from LaTeX, removing the
superfluous re-build for every git revision change (even when no relevant spec
file changed).

Isabelle2020 requires each session to declare it own set of directories that
may not overlap with other session's directories. This commit reorganises
files to comply with that requirement.

Session-qualified imports will be required for Isabelle2018 and help clarify
the structure of sessions in the build tree.
This commit mainly adds a new set of sessions for lib/, including a Lib
session that includes most theories in lib/ and a few separate sessions for
parts that have dependencies beyond CParser or are separate AFP sessions.
The group "lib" collects all lib/ sessions.
As a consequence, other theories should use lib/ theories by session name,
not by path, which in turns means spec and proof sessions should also refer
to each other by session name, not path, to avoid duplicate theory errors in
theory merges later.
Including version information in the spec document is tricky, because
Isabelle will rebuild the session whenever it sees that session inputs
(including document sources) have changed. Since ASpec is close to the
root of our session hierarchy, frequently changing version information
causes excessive rebuilds during development.
This commit avoids excessive rebuilding by building the document (with
version information) in a separate ASpecDoc session. The ASpecDoc
session is identical to the previous version of the ASpec session, but
is not the parent of any other sessions. The ASpec session is used as
the basis for other sessions, but has document-only inputs removed, and
also has document builds disabled.
This partially reverts a recent change which adds these.
Unfortunately, including the ARCH and git-id files in the ROOT file
causes frequent rebuilds during development. For example, adding a
commit that changes only CRefine would cause a change in the git-id
file, which would in turn trigger a rebuild of ASpec and everything that
depends on it. Because the git-id file also noted uncommitted changes,
these would also trigger an ASpec rebuild. Similarly, switching to a
different L4V_ARCH would cause the ARCH file to change, also triggering
an ASpec rebuild.
Since Isabelle makes it difficult to include this information in the
document without adding these files to the ROOT file, this commit is
removing this information until we find a better way.
Removes files that were duplicated in cspec/$L4V_ARCH directories to exist directly in
the cspec directory and contain $L4V_ARCH switches where needed. This allows for a single
Makefile for building the C kernel and the KernelInc_C theory, which is different between
architectures, to still exist per L4V_ARCH.
As the build location of the C kernel, and the resulting kernel_all.c_pp artifact, is
moved this change needs to be reflected in all the theory files that refer to it.
