The 'record' and 'top' tools already allow a user to specify a CSV of
pids and/or tids of tasks to collect data.

Add those options to the 'report' and 'script' analysis commands to only
consider samples related to the given pids/tids.

This is also inline with the existing comm option.

Example:

Before this patch:

 $ perf script <TAB>

As shown above, the subsubcommands of perf script does not come out.

After this patch:

 $ perf script <TAB>

As shown above, the subsubcommands of perf script can come out now.

Currently vmlinux_path__init() only tries to find vmlinux file from
current directory, /boot and some canonical directories with version
number of the running kernel.  This can be a problem when reporting old
data recorded on a kernel version not running currently.

We can use --symfs option for this but it's annoying for user to do it
always.  As we already have the info in the perf.data file, it can be
changed to use it for the search automatically.

Before:

  $ perf report
  ...
  # Samples: 4K of event 'cpu-clock'
  # Event count (approx.): 1067250000
  #
  # Overhead  Command     Shared Object      Symbol
  # ........  ..........  .................  ..............................
      71.87%     swapper  [kernel.kallsyms]  [k] recover_probed_instruction

After:

  # Overhead  Command     Shared Object      Symbol
  # ........  ..........  .................  ....................
      71.87%     swapper  [kernel.kallsyms]  [k] native_safe_halt

This requires to change signature of symbol__init() to receive struct
perf_session_env *.

Change the order of the output to put the srcline last.

It puts the branch 'from address' and 'to address' on the same line,
which is how it would be without the source line reference.

So it makes it consistent and much easier to read.

E.g. old format:

          4028fc main+0x2c (/bin/ls)
  /build/buildd/coreutils-8.20/src/ls.c:1269 =>           40d8a0 set_program_name+0x0 (/bin/ls)

new format:

          4028fc main+0x2c (/bin/ls) =>           40d8a0 set_program_name+0x0 (/bin/ls)

The addr_location struct should fully qualify an address, and to do that
it should have in it the machine where the thread was found.

Thus all functions that receive an addr_location now don't need to also
receive a 'machine', those functions just need to access al->machine
instead, just like it does with the other parts of an address location:
al->thread, al->map, etc.

Attributes (struct perf_event_attr) are recorded separately in the
perf.data file.  perf script uses them to set up output options.
However attributes can also be in the event stream, for example when the
input is a pipe (i.e. live mode).  This patch makes perf script process
in-stream attributes in the same way as on-file attributes.

Here is an example:

Before this patch:

$ perf record uname | perf script

[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.015 MB (null) (~655 samples) ]

After this patch:

As the thread comm is going to be implemented by way of a more
complicated data structure than just a pointer to a string from the
thread struct, convert the readers of comm to use an accessor instead of
accessing it directly.

The accessor will be later overriden to support an enhanced comm
implementation.

This patch adds support for the new PERF_RECORD_MMAP2 record type
exposed by the kernel. This is an extended PERF_RECORD_MMAP record.

It adds for each file-backed mapping the device major, minor number and
the inode number and generation.

This triplet uniquely identifies the source of a file-backed mapping. It
can be used to detect identical virtual mappings between processes, for
instance.

The patch will prefer MMAP2 over MMAP.
