The perf script command uses various expressions to indicate "unknown".
It is unfriendly for user scripts to parse it. So, this patch unifies
the expressions to "[unknown]".

BTS records branch_from_addr and branch_to_addr in IP and ADDR field in perf_sample.
This patch enables to print them in following format,
<from_addr> <from_symbol> (<from_dso>) => <to_addr> <to_symbol> (<to_dso>)
Sample:
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e016b0 _start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e016b0 _start (/lib64/ld-2.14.so)
3f03e016b3 _start (/lib64/ld-2.14.so) => 3f03e04b80 _dl_start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e04b80 _dl_start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e04ba6 _dl_start (/lib64/ld-2.14.so)
ffffffff814675d2 irq_return ([kernel.kallsyms]) => 3f03e04bad _dl_start (/lib64/ld-2.14.so)

Add the offset field specifier 'symoff' to show the offset from
the symbols in the output of perf-script. We can get the more
detailed address information.
Output sample:
ffffffff81467612 irq_return+0x0 => 301ec016b0 _start+0x0
ffffffff81467612 irq_return+0x0 => 301ec016b0 _start+0x0

ffffffff81467612 irq_return+0x0 => 301ec04b70 _dl_start+0x0
ffffffff81467612 irq_return+0x0 => 301ec04b96 _dl_start+0x26
ffffffff81467612 irq_return+0x0 => 301ec04b9d _dl_start+0x2d
301ec04beb _dl_start+0x7b => 301ec04c0d _dl_start+0x9d

From: Stephane Eranian <eranian@google.com>
In recent versions of perf top, pressing the 'e' key to change the
number of displayed samples had no effect.
The number of samples was still dictated by the size of the terminal
(stdio mode). That was quite annoying because typically only the first
dozen samples really matter.
This patch fixes this.

There are unnecessary #include <ctype.h> out there, and they might cause
a nasty build failure in some environment. As we already have most of
ctype macros in util.h, just get rid of them.
A few of exceptions are util/symbol.c which needs isupper() macro util.h
doesn't provide and perl scripting support code which includes ctype.h
internally.

is only for PERF_RECORD_SAMPLE, so also use attr.watermark = 1 to fix
that.
