perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/

Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.

+# The default target of this Makefile is...
+all::
+
+# Define V=1 to have a more verbose compile.
+#
+# Define SNPRINTF_RETURNS_BOGUS if your are on a system which snprintf()
+# or vsnprintf() return -1 instead of number of characters which would
+# have been written to the final string if enough space had been available.
+#
+# Define FREAD_READS_DIRECTORIES if your are on a system which succeeds
+# when attempting to read from an fopen'ed directory.
+#
+# Define NO_OPENSSL environment variable if you do not have OpenSSL.
+# This also implies MOZILLA_SHA1.
+#
+# Define CURLDIR=/foo/bar if your curl header and library files are in
+# /foo/bar/include and /foo/bar/lib directories.
+#
+# Define EXPATDIR=/foo/bar if your expat header and library files are in
+# /foo/bar/include and /foo/bar/lib directories.
+#
+# Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
+#
+# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
+# d_type in struct dirent (latest Cygwin -- will be fixed soonish).
+#
+# Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
+# do not support the 'size specifiers' introduced by C99, namely ll, hh,
+# j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
+# some C compilers supported these specifiers prior to C99 as an extension.
+#
+# Define NO_STRCASESTR if you don't have strcasestr.
+#
+# Define NO_MEMMEM if you don't have memmem.
+#
+# Define NO_STRTOUMAX if you don't have strtoumax in the C library.
+# If your compiler also does not support long long or does not have
+# strtoull, define NO_STRTOULL.
+#
+# Define NO_SETENV if you don't have setenv in the C library.
+#
+# Define NO_UNSETENV if you don't have unsetenv in the C library.
+#
+# Define NO_MKDTEMP if you don't have mkdtemp in the C library.
+#
+# Define NO_SYS_SELECT_H if you don't have sys/select.h.
+#
+# Define NO_SYMLINK_HEAD if you never want .perf/HEAD to be a symbolic link.
+# Enable it on Windows.  By default, symrefs are still used.
+#
+# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
+# tests.  These tests take up a significant amount of the total test time
+# but are not needed unless you plan to talk to SVN repos.
+#
+# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
+# installed in /sw, but don't want PERF to link against any libraries
+# installed there.  If defined you may specify your own (or Fink's)
+# include directories and library directories by defining CFLAGS
+# and LDFLAGS appropriately.
+#
+# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
+# have DarwinPorts installed in /opt/local, but don't want PERF to
+# link against any libraries installed there.  If defined you may
+# specify your own (or DarwinPort's) include directories and
+# library directories by defining CFLAGS and LDFLAGS appropriately.
+#
+# Define PPC_SHA1 environment variable when running make to make use of
+# a bundled SHA1 routine optimized for PowerPC.
+#
+# Define ARM_SHA1 environment variable when running make to make use of
+# a bundled SHA1 routine optimized for ARM.
+#
+# Define MOZILLA_SHA1 environment variable when running make to make use of
+# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
+# on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
+# choice) has very fast version optimized for i586.
+#
+# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
+#
+# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
+#
+# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
+# Patrick Mauritz).
+#
+# Define NO_MMAP if you want to avoid mmap.
+#
+# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
+#
+# Define NO_PREAD if you have a problem with pread() system call (e.g.
+# cygwin.dll before v1.5.22).
+#
+# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
+# generally faster on your platform than accessing the working directory.
+#
+# Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
+# the executable mode bit, but doesn't really do so.
+#
+# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
+#
+# Define NO_SOCKADDR_STORAGE if your platform does not have struct
+# sockaddr_storage.
+#
+# Define NO_ICONV if your libc does not properly support iconv.
+#
+# Define OLD_ICONV if your library has an old iconv(), where the second
+# (input buffer pointer) parameter is declared with type (const char **).
+#
+# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
+#
+# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
+# that tells runtime paths to dynamic libraries;
+# "-Wl,-rpath=/path/lib" is used instead.
+#
+# Define USE_NSEC below if you want perf to care about sub-second file mtimes
+# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
+# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
+# randomly break unless your underlying filesystem supports those sub-second
+# times (my ext3 doesn't).
+#
+# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
+# "st_ctim"
+#
+# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
+# available.  This automatically turns USE_NSEC off.
+#
+# Define USE_STDEV below if you want perf to care about the underlying device
+# change being considered an inode change from the update-index perspective.
+#
+# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
+# field that counts the on-disk footprint in 512-byte blocks.
+#
+# Define ASCIIDOC8 if you want to format documentation with AsciiDoc 8
+#
+# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72.
+#
+# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
+# MakeMaker (e.g. using ActiveState under Cygwin).
+#
+# Define NO_PERL if you do not want Perl scripts or libraries at all.
+#
+# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
+# is a simplified version of the merge sort used in glibc. This is
+# recommended if Git triggers O(n^2) behavior in your platform's qsort().
+#
+# Define NO_EXTERNAL_GREP if you don't want "perf grep" to ever call
+# your external grep (e.g., if your system lacks grep, if its grep is
+# broken, or spawning external process is slower than built-in grep perf has).
