2b3e390674 util: virstring: Remove virStringListAdd and virStringListRemove
virStringListAdd hides the fact that a O(n) count of elements is

Stop supporting such semantics and remove the helpers. Users have a
choice of using GSList or an array with a counter variable rather than
repeated lookups.

2621d48f00 gnulib: delete all gnulib integration
This deletes all trace of gnulib from libvirt. We still
have the keycodemapdb submodule to deal with. The simple
solution taken was to update it when running autogen.sh.

Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
about, given how infrequently keycodemapdb changes.

600462834f Remove all Author(s): lines from source file headers
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 IOW, the Author: comments are quickly out of date,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.

f18c02ec22 util: fix uint parsing on 64-bit platforms
Commit f22b7899 called to light a long-standing latent bug: the
behavior of virStrToLong_ui was different on 32-bit platforms
than on 64-bit platforms.  Curse you, C type promotion and
narrowing rules, and strtoul specification.  POSIX says that for
a 32-bit long, strtol handles only 2^32 values [LONG_MIN to
LONG_MAX] while strtoul handles 2^33 - 1 values [-ULONG_MAX to
ULONG_MAX] with twos-complement wraparound for negatives.  Thus,
parsing -1 as unsigned long produces ULONG_MAX, rather than a
range error.  We WANT[1] this same shortcut for turning -1 into
UINT_MAX when parsing to int; and get it for free with 32-bit
long.  But with 64-bit long, ULONG_MAX is outside the range
of int and we were rejecting it as invalid; meanwhile, we were
silently treating -18446744073709551615 as 1 even though it
textually exceeds INT_MIN.  Too bad there's not a strtoui() in
libc that does guaranteed parsing to int, regardless of the size
of long.

The bug has been latent since 2007, introduced by Jim Meyering
in commit 5d25419 in the attempt to eradicate unsafe use of
strto[u]l when parsing ints and longs.  How embarrassing that we
are only discovering it now - so I'm adding a testsuite to ensure
that it covers all the corner cases we care about.

[1] Ideally, we really want the caller to be able to choose whether
to allow negative numbers to wrap around to their 2s-complement
counterpart, as in strtoul, or to force a stricter input range
of [0 to UINT_MAX] by rejecting negative signs; this will be added
in a later patch for all three int types.

This patch is tested on both 32- and 64-bit; the enhanced
virstringtest passes on both platforms, while virstoragetest now
reliably fails on both platforms instead of just 32-bit platforms.
That test will be fixed later.

* src/util/virstring.c (virStrToLong_ui): Ensure same behavior
regardless of platform long size.
* tests/virstringtest.c (testStringToLong): New function.
(mymain): Comprehensively test string to long parsing.
