And pick the shortest name: 'struct maps'.

The split existed because we used to have two groups of maps, one for
functions and one for variables, but that only complicated things,
sometimes we needed to figure out what was at some address and then had
to first try it on the functions group and if that failed, fall back to
the variables one.

That split is long gone, so for quite a while we had only one struct
maps per struct map_groups, simplify things by combining those structs.

First patch is the minimum needed to merge both, follow up patches will
rename 'thread-&gt;mg' to 'thread-&gt;maps', etc.

<title>libperf: Move 'page_size' global variable to libperf</title>

We need the 'page_size' variable in libperf, so move it there.

Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.

Committer notes:

Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.

So that we can reduce the header dependency tree further, in the process
noticed that lots of places were getting even things like build-id
routines and 'struct perf_tool' definition indirectly, so fix all those
too.

<title>perf test vmlinux-kallsyms: Ignore aliases to _etext when searching on kallsyms</title>

No need to search for aliases for the symbol that marks the end of the
kernel text segment, the following patch will make such symbols not to
be found when searching in the kallsyms maps causing this test to fail.

So as a prep patch to avoid breaking bisection, ignore such symbols.
