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 IOW, the Author: comments are quickly out of date,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

The `if(!list || list->type != VIR_CONF_LIST)` check couldn't be
written in a 100% similar way. Instead, we're just checking whether
`virConfGetValueStringList() <= 0` and creating a new function to:
- return -1 in case virConfGetValueStringList fails either due to some
allocation failure or when traversing the list;
- resetting the last error and return 0 otherwise;
Taking this approach we can have the behaviour with the new code as
close as possible to the old one.

This change actually changes the behaviour of xenConfigGetString() as
now it returns a newly-allocated string.
Unfortunately, there's not much that can be done in order to avoid that
and all the callers have to be changed in order to avoid leaking the
return value.
Also, as a side-effect of the change above, the function now takes a
"char **" argument instead of a "const char **" one.

Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.
Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.
Change the functions so that they return an int
instead.

The strncpy() function has this quirk where it will copy
*up* to the requested number of bytes, that is, it will
stop early if it encounters a NULL byte in the source
string.
This makes it legal to pass the size of the destination
buffer (minus one byte needed for the string terminator)
as the number of bytes to copy and still get something
somewhat reasonable out of the operation; unfortunately,
it also makes the function difficult to reason about
and way too easy to misuse.
We want to move away from the way strncpy() behaves and
towards better defined semantics, where virStrncpy()
will always copy *exactly* the number of bytes it's
been asked to copy; before we can do that, though, we
have to change a few of the callers.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
This convenience macro was created for the simple cases
where the length of the source string and the size of the
destination buffer can be figued out with strlen() and
sizeof() respectively, so we should use it wherever
possible instead of open-coding parts of it.

xenParseVif() does a lot of stuff and, in order to make things cleaner,
let's split it in two new functions:
- xenParseVif(): it's a new function that keeps the old name. It's
responsible for the whole per-Vif logic from the old xenParseVif();
- xenParseVifList(): it's basically the old xenParsePCI(), but now it
just iterates over the list of Vifs, calling xenParsePCI() per each Vif.

typesafe virConf acessors will be used.

Convert CPU features policy into libxl cpuid policy settings. Use new

accepted.
Libxl do not have distinction between "force" and "required" policy
(there is only "force") and also between "forbid" and "disable" (there
is only "disable"). So, merge them appropriately. If anything, "require"
and "forbid" should be enforced outside of specific driver.
Nested HVM (vmx and svm features) is handled separately, so exclude it
