Allow vTPM state encryption when swtpm_setup and swtpm support
passing a passphrase using a file descriptor.
This patch enables the encryption of the vTPM state only. It does
not encrypt the state during migration, so the destination secret
does not need to have the same password at this point.

Move qemuTPMEmulatorInit to virTPMEmulatorInit in virtpm.c and introduce
a few functions to query the executables needed for virCommands.
Add locking to protect the tool paths and return a copy of the tool paths
to callers wanting to access them so that we can run the initialization
function multiples time later on and detect when the executable gets updated.

In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.
With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to find the
author of a particular bit of code.
This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.
The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

This patch addresses BZ 1244895.
Adapt the sysfs TPM command cancel path for the TPM driver that

Add a mockup for the test cases to avoid the testing for

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
