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 IOW, the Author: comments are quickly out of date,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.

All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

Since it's not longer used to shuttle the @secinfo, let's remove
the private hostdev completely.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

So the hostdev manager has some lists to keep track which devices
are active (=assigned to a domain) or inactive. The manager and
its lists are allocated in myInit and freed in myCleanup but one
of them (activeSCSIHostdevs) was missing. Also, the order in
which the cleanup was done doesn't make it easy to spot it,
therefore reoder it.

All other virDomain*Def follow this naming convention for
their allocation function.

We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

This function doesn't follow our convention of naming functions.

Modeled after the qemuDomainDiskPrivatePtr logic, create a privateData
pointer in the _virDomainHostdevDef to allow storage of private data
for a hypervisor in order to at least temporarily store auth/secrets
data for usage during qemuBuildCommandLine.

NB: Since the qemu_parse_command (qemuParseCommandLine) code is not
expecting to restore the auth/secret data, there's no need to add
code to handle this new structure there.

Ensure the code behaves properly even for situations that were not
being considered before, such as simply detaching devices from the
host without attaching them to a guest and attaching devices as
managed even though they had already been manually detached from
the host.

Instead of considering each single step its own test case, create
high level test cases that reproduce a certain scenario.

Always call CHECK_LIST_COUNT() to check the size of both the active
and inactive devices list.

virPCIDeviceListCount()'s return type is size_t, so variables that
store its return value should be of that type.

The 'actualCount' variable, formerly just 'count', is only used
internally by the macro, so it's better to move its declaration
inside the macro as well: this way, it doesn't have to be declared
by every single user.

The new name is less generic to make clashes less likely.

Change the extremely generic count1 and count2 to the more
descriptive active_count and inactive_count.

When checking the number of devices added to a device list, use the
nhostdevs variable instead of its value, so that the test can keep
working even if more hostdevs are added.

No functional changes.

This replaces the virPCIKnownStubs string array that was used
internally for stub driver validation.

Advantages:

  * possible values are well-defined
  * typos in driver names will be detected at compile time
  * avoids having several copies of the same string around
  * no error checking required when setting / getting value

The names used mirror those in the
virDomainHostdevSubsysPCIBackendType enumeration.

The old name is no longer accurate, since now we're using its value as
the root of the fake filesystem.

No functional changes.

VIR_DEBUG and VIR_WARN will automatically add a new line to the message,
having "\n" at the end or at the beginning of the message results in

Commit id 'f1f68ca3' added code to remove the directory paths for
auto-generated sockets, but that code could be called before the
paths were created resulting in generating error messages from
virFileDeleteTree indicating that the file doesn't exist.

Rather than "enforce" all callers to make the non-NULL and existence
checks, modify the virFileDeleteTree API to silently ignore NULL on
input and non-existent directory trees.

C guarantees that static variables are zero-initialized.  Some older
compilers (and also gcc -fno-zero-initialized-in-bss) create larger
binaries if you explicitly zero-initialize a static variable.
