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.

It is no longer needed thanks to the great virfilewrapper.c.  And this
way we don't have to add a new set of functions for each prefixed
path.

While on that, add two functions that weren't there before, string and
scaled integer reading ones.  Also increase the length of the string
being read by one to accompany for the optional newline at the
end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).

This mock (which is actually not mock at all, see later) can redirect
all accesses to a path into another path.  There is no need to
create mocks for particular directories, you just create a directory
with all the data a redirect the test there.

In the future, this should also be able to register callbacks for
calls/paths, e.g. when the test is going to write into anything under
"/sys/devices", call function fce();  Then in the open() call we would
add information about the fd into some structure and in write() we
would call fce() with parameters like @path to write to, @data to
be written and pointer to optional return value, so that fce() itself
could stop the call from happening or change its behaviour.  But
that's an idea for a latter day.

This is not a mock because it will not be preloaded, but compiled in
the test itself.  See future patches for usage.

A previous commit changed the spec to use librbd1-devel on
RHEL-7, since this replaces ceph-devel from RHEL-6:

  commit 6cfc8834
  Author: Peter Krempa <pkrempa@redhat.com>
  Date:   Thu Mar 5 11:40:54 2015 +0100

    spec: Enable RBD storage driver in RHEL-7

    Use correct package names too as they differ.

RHEL-7 inherited this rename from Fedora though, so it should
have also made Fedora use the new names.

This was missed, because Fedora still provides a (deprecated)
back-compat RPM for ceph-devel that just pulls in librbd1-devel
(and others).

Fixing this stops libvirt pulling Java into the build root in
Fedora.
