512fe36537 perf tools: define _DEFAULT_SOURCE for glibc_2.20 
_BSD_SOURCE was deprecated in favour of _DEFAULT_SOURCE since glibc
2.20[1]. To avoid build warning on glibc2.20, _DEFAULT_SOURCE should
also be defined.

  Error:
  The PMU counters are busy/taken by another profiler.
  We found oprofile daemon running, please stop it and try again.

In case oprofiled was not detected the current error message stays:

  /bin/dmesg may provide additional information.

in case of EBUSY error, as it currently does:

  $ perf record ls
  Error:

  perf_event_open(..., 0) failed unexpectedly with error 16 (Device or resource busy)

553873e1df tools/: Convert to new topic libraries 
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.

1dbfa9387b perf evlist: Fix mmap pages rounding to power of 2 
'next_pow2()' only works for 'unsigned int' but the argument is
'unsigned long'.  Checking for values less than (1 << 31) ensures that
'next_pow2()' is not passed a value out of range but lets anything else
go through unvalidated.

As a result mmap_pages of zero is used e.g.

  perf record -v -m2147483649 uname
  mmap size 0B
  failed to mmap with 22 (Invalid argument)

Fixed:

  perf record -m2147483649 uname
  rounding mmap pages size to 17592186044416 bytes (4294967296 pages)
  Invalid argument for --mmap_pages/-m

756bbc84e3 perf tools: Include termios.h explicitly 
Building perf for android fails because it can't find the definition of
struct winsize.

This definition is in termios.h, so I add this header to util.h to solve
the problem.

It is missed by commit '2c803e52' which moves get_term_dimensions() from
builtin-top.c to util.c, but missed to move termios.h header.
