perf buildid: add perfconfig option to specify buildid cache dir
This patch adds the ability to specify an alternate directory to store the
buildid cache (buildids, copy of binaries). By default, it is hardcoded to
$HOME/.debug. This directory contains immutable data. The layout of the
directory is such that no conflicts in filenames are possible. A modification
in a file, yields a different buildid and thus a different location in the
subdir hierarchy.
You may want to put the buildid cache elsewhere because of disk space
limitation or simply to share the cache between users. It is also useful for
remote collect vs. local analysis of profiles.
This patch adds a new config option to the perfconfig file. Under the tag
'buildid', there is a dir option. For instance, if you have:
$ cat /etc/perfconfig
[buildid]
dir = /var/cache/perf-buildid
All buildids and binaries are be saved in the directory specified. The perf
record, buildid-list, buildid-cache, report, annotate, and archive commands
will it to pull information out.
The option can be set in the system-wide perfconfig file or in the
$HOME/.perfconfig file.

perf tui: Allow disabling the TUI on a per command basis in ~/.perfconfig
Using the same scheme as for git's/perf's pager setup, i.e. if one
doesn't want to, on a newt enabled perf binary, to disable the TUI for
'perf report', its just a matter of doing:
[root@doppio linux-2.6-tip]# printf "[tui]\n\nreport = off\n" >
/root/.perfconfig
[root@doppio linux-2.6-tip]# cat /root/.perfconfig
[tui]
report = off
[root@doppio linux-2.6-tip]#
System wide settings are also possible, by editing /etc/perfconfig, etc,
i.e. the git machinery for config files applies to perf as well, so when
in doubt where to put your settings, consult the git documentation, if
it fails, please let us know.
