In a few places our code relies on the fact that virAsprintf()
not only prints to allocated string but also that it returns the
length of that string. Fortunately, only few such places were
identified:
https://www.redhat.com/archives/libvir-list/2019-September/msg01382.html
In case of virNWFilterSnoopLeaseFileWrite() and virFilePrintf()
we can use strlen() right after virAsprintf() to calculate the
length. In case of virDoubleToStr() it's only caller checks for
error case only, so we can limit the set of returned values to
just [-1, 0].

Convert the string duplication APIs to use the g_strdup family of APIs.
We previously used the 'strdup-posix' gnulib module because mingw does
not set errno to ENOMEM on failure
We previously used the 'strndup' gnulib module because this function

We previously used the 'vasprintf' gnulib module because of many GNU
supported format specifiers not working on non-Linux platforms. glib's

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 IOW, the Author: comments are quickly out of date,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

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.

../../src/util/virfile.c:3987: error: called from here [-Winline]
Inlining this function is not going to be a measurable performance
benefit either, since the time required to execute it is going to
be dominated by running of strlen() over the string, not by the
function call overhead.
