The name analyzer is the actual work horse of the tokenizer. It
is instantiated on a thread-base and provides all functions for

Indexing is now split into three parts: first a preparation step
that collects the necessary information from the database and
returns it to Python. In a second step the data is transformed
within Python as necessary and then returned to the database
through the usual UPDATE which now not only sets the indexed_status
but also other fields. The third step comprises the address
computation which is still done inside the update trigger in
the database.
The second processing step doesn't do anything useful yet.
On Windows systems the timer may not be accurate enough to measure
the time between init() and done(). Avoid computing statistics with
a diff time of 0 in such cases.
Fixes#2230.
The PHP scripts need to know the position of the nominatim
tool in order to call it. This is handed in as environment
variable, so it can be set by the Python script.
Wait for 2 seconds before logging the first progress, so that we
have numbers that are a bit more reliable statistically speaking.
Also provides an actual implementation for the log_interval
parameter and fixes some small style issues.
