Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.
For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.
acme:
"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.
But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."
Fixup documentation cleaning target while at it.

The compilation only looks for linux/magic.h from the default include
paths, which does not include the source tree. This results in a build
error if linux/magic.h is not available or not installed.
For example, this build error occurs on CentOS 5.
$ make -C tools/lib/lk V=1
[...]
gcc -o debugfs.o -c -ggdb3 -Wall -Wextra -std=gnu99 -Werror -O6
-D_FORTIFY_SOURCE=2 -Wbad-function-cast -Wdeclaration-after-statement
-Wformat-security -Wformat-y2k -Winit-self -Wmissing-declarations
-Wmissing-prototypes -Wnested-externs -Wno-system-headers
-Wold-style-definition -Wpacked -Wredundant-decls -Wshadow
-Wstrict-aliasing=3 -Wstrict-prototypes -Wswitch-default -Wswitch-enum

-D_FILE_OFFSET_BITS=64 debugfs.c
debugfs.c:8:25: error: linux/magic.h: No such file or directory
The only symbol from linux/magic.h needed by debugfs.c is DEBUGFS_MAGIC,
and that is already defined in debugfs.h. linux/magic.h isn't providing
any extra symbols and can unincluded. This is similar to the approach by
perf, which has its own magic.h wrapper at
tools/perf/util/include/linux/magic.h

Move them to util.c and simplify code a bit.

This introduces the tools/lib/lk library, that will gradually have the
routines that now are used in tools/perf/ and other tools and that can
be shared.
Start by carving out debugfs routines for general use.

[ committer note: Add tools/lib/lk/ to perf's MANIFEST so that its tarballs continue to build ]
