Thru series of refactorings functions were being renamed but not
moved to map.c to reduce patch noise, now lets have them in the
same place so that use of the symbol system by tools can be
constrained to building and linking fewer source files:
symbol.c, map.c and rbtree.c.

That will be in both struct hist_entry and struct
callchain_list, so that the TUI can store a pointer to the pair
(map, symbol) in the trees where hist_entries and
callchain_lists are present, to allow precise annotation instead
of looking for the first symbol with the selected name.

We were performing the full thread__find_addr_location
operation, i.e. resolving to a map/dso _and_ loading its symbols
when we can optimize it by first calling thread__find_addr_map
to find just the map/dso, check if it is one that we are
interested in (passed via --dsos/-d in 'perf annotate', 'perf
report', etc) and if not avoid loading the symtab.

Nice speedup when we know which DSO we're interested in.

The adding of raw event support lead to complete code
refactoring. I hope is became more readable then it was.

The list of changes:

1)  The 64bit config field is enough to hold all information we need
    to track event details. To achieve it we used *own* enum for
    events selection in ESCR register and map this key into proper
    value at moment of event enabling.

    For the same reason we use 12LSB bits in CCCR register -- to track
    which exactly cache trace event was requested. And we cear this bits
    at real 'write' moment.

2)  There is no per-cpu area reserved for P4 PMU anymore. We
    don't need it. All is held by config.

3)  Now we may use any available counter, ie we try to grab any
    possible counter.

v2:
  - Lin Ming reported the lack of ESCR selector in CCCR for cache events

v3:
  - Don't loose cache event codes at config unpacking procedure, we may
    need it one day so no obscure hack behind our back, better to clear
    reserved bits explicitly when needed (thanks Ming for pointing out)

  - Lin Ming fixed misplaced opcodes in cache events

the symbol, be it the top level one or any of the symbols in the
chains.

It (ab)uses the only tree widget in newt, that is actually a
checkbox tree that we use with just one option ('.'), end result
is usable but we really need to create a custom widget tree so
that we can use the data structures we have (hist_entry rb_tree
+ callchain rb_tree + lists), so that we reduce the memory
footprint by not creating a mirror set of data structures in the
newtCheckboxTree widget.

Callchains have markers inside their capture to tell we
enter a context (kernel, user, ...).

Those are not displayed in the callchains but they are
incidentally an active part of the radix tree where
callchains are stored, just like any other address.

If we have the two following callchains:

addr1 -> addr2 -> user context -> addr3
addr1 -> addr2 -> user context -> addr4
addr1 -> addr2 -> addr 5

This is pretty common if addr1 and addr2 are part of an
interrupt path, addr3 and addr4 are user addresses and
addr5 is a kernel non interrupt path.

This will be stored as follows in the tree:

                   addr1
                   addr2
                   /   \
                  /     addr5
            user context
               /    \
             addr3  addr4

But we ignore the context markers in the report, hence
the addr3 and addr4 will appear as orphan branches:

    |--28.30%-- hrtimer_interrupt
    |          smp_apic_timer_interrupt
    |          apic_timer_interrupt
    |          |           <------------- here, no parent!
    |          |          |
    |          |          |--11.11%-- 0x7fae7bccb875
    |          |          |
    |          |          |--11.11%-- 0xffffffffff60013b
    |          |          |
    |          |          |--11.11%-- __pthread_mutex_lock_internal
    |          |          |
    |          |          |--11.11%-- __errno_location

Fix this by removing the context markers when we process the
callchains to the tree.

USB 3 and Wireless USB specify a logarithmic encoding of the endpoint

know that and was filling in the interval as if it was USB 1.1.  Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.

Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.

Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently.  This allows xHCI roothubs to actually register with khubd.
