We can use STRNEQ() instead of STRNEQLEN() since we're only
interested in the trailing part of the string and we've
already verified that the length of file, name and suffix
are those we expect.

While this function is not, strictly speaking, a predicate,
it still mostly behaves like one as evidenced by the vast
majority of its callers, so using bool rather than int as
the return type makes sense.

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 IOW, the Author: comments are quickly out of date,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

This commit fixes a locale problem with locales that use comma as a mantissa
separator. Example: 12.34 en_US = 12,34 pt_BR. Since strtod() is a non-safe
function, virStrToDouble() will have problems to parse double numbers from
kernel settings and other double numbers from static files (XMLs, JSONs, etc).

GCC complains that inlining virStringTrimOptionalNewline is not
likely on some platforms:
cc1: warnings being treated as errors
../../src/util/virfile.c: In function 'virFileReadValueBitmap':
../../src/util/virstring.h:292: error: inlining failed in call to 'virStringTrimOptionalNewline': call is unlikely and code size would grow [-Winline]
../../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.

The first argument should be const char ** instead of
char **, because this is a search function and as such it
doesn't, and shouldn't, alter the haystack in any way.
This change means we no longer have to cast arrays of
immutable strings to arrays of mutable strings; we still
have to do the opposite, though, but that's reasonable.
The virStringListLength function does not ever modify the passed
string list. It merely counts the items in it. Make sure that we
reflect this bit in the function header.

In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.

Add virStringHasControlChars that checks if the string has
any control characters other than \t\r\n,
and virStringStripControlChars that removes them in-place.
The helper checks whether a string contains only whitespace or is NULL.
This will be helpful to skip cases where a user string is optional, but
may be provided empty with the same meaning.
