perf script python: Add support for exporting to sqlite3 

Add support for exporting to SQLite 3 the same data as the PostgreSQL
export.

Committer note:

Tested on RHEL 7.4 using the 1.2.2-4el python-pyside packages from EPEL.

unpack the raw data for power events and PTWRITE.

# To use this script you will need to have installed package python-pyside which

# libqt4-sql-sqlite for Qt sqlite3 support.
#
# An example of using this script with Intel PT:
#
# $ perf record -e intel_pt//u ls
# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py pt_example branches calls

# To browse the database, sqlite3 can be used e.g.

# $ sqlite3 pt_example

# sqlite> select * from samples_view where id < 10;
# sqlite> .mode column
# sqlite> select * from samples_view where id < 10;
# sqlite> .tables
# sqlite> .schema samples_view
# sqlite> .quit

# An example of using the database is provided by the script
# call-graph-from-sql.py. Refer to that script for details.
#
# The database structure is practically the same as created by the script
# export-to-postgresql.py. Refer to that script for details. A notable
# difference is the 'transaction' column of the 'samples' table which is
# renamed 'transaction_' in sqlite because 'transaction' is a reserved word.
