Arnaldo Carvalho de Melo b83e868d0a perf db-export: No need to have ->thread twice in struct export_sample
As it comes from address_location->thread, that is already stored as
export_sample->al, where the thread can be obtained.

Adrian Hunter 758008b262 perf tools: Defer export of comms that were not 'set'
Tracing for a workload begins before the comm event is seen, which
results in the initial comm having a string of the form ":<pid>" (e.g.
":12345").

In order to export the correct string, defer the export until the new
script 'flush' callback.

Adrian Hunter 0db15b1e84 perf tools: Add facility to export data in database-friendly way
This patch introduces an abstraction for exporting sample data in a
database-friendly way.  The abstraction does not implement the actual
output.  A subsequent patch takes this facility into use for extending
the script interface.

The abstraction is needed because static data like symbols, dsos, comms
etc need to be exported only once.  That means allocating them a unique
identifier and recording it on each structure.  The member 'db_id' is
used for that.  'db_id' is just a 64-bit sequence number.

Exporting centres around the db_export__sample() function which exports
the associated data structures if they have not yet been allocated a
db_id.
