This patch gives users the option to set a `"prefix"` attribute
for Python applications, either at the top level or for specific
`"target"`s. If the attribute is present, the value of `"prefix"`
must be a string beginning with `"/"`. If the value of the `"prefix"`
attribute is longer than 1 character and ends in `"/"`, the
trailing `"/"` is stripped.
The purpose of the `"prefix"` attribute is to set the `SCRIPT_NAME`
context value for WSGI applications and the `root_path` context
value for ASGI applications, allowing applications to properly route
requests regardless of the path that the server uses to expose the
application.
The context value is only set if the request's URL path begins with
the value of the `"prefix"` attribute. In all other cases, the
`SCRIPT_NAME` or `root_path` values are not set. In addition, for
WSGI applications, the value of `"prefix"` will be stripped from
the beginning of the request's URL path before it is sent to the
application.

This is a preparatory patch that renames the 'local' and 'local_length'
members of the nxt_unit_request_t structure to 'local_addr' and
'local_addr_length' in preparation for the adding of 'local_port' and
'local_port_length' members.

Unit's ASGI implementation creates a new event loop to run an application for
each thread since 542b5b8c0647. This may cause unexpected exceptions or
strange bugs if asyncio synchronisation primitives are initialised before the
application starts (e.g. globally).
Although the approach with a new event loop for the main thread is consistent
and helps to prepare the application to run in multiple threads, it can be a
source of pain for people who just want to run single-threaded ASGI
applications in Unit.
This is related to #560 issue on GitHub.

The WSGI environment dictionary contains a number of static items, that are
pre-initialized on application start. Then it's copied for each request to be
filled with request-related data.
Now this dictionary copy operation will be done between processing of requests,
which should save some CPU cycles during request processing and thus reduce
response latency for non-peak load periods.

PyUnicode_GET_SIZE() in deprecated since 3.3 and will be removed in 3.12.
In version 3.9 it was explicitly marked by deprecation warning causing
compilation error with Unit.
PyUnicode_GET_LENGTH() must be used instead.

The coming ASGI support requires raw HTTP headers format. Headers grouping
and upcase code were moved to WSGI module.

This is required for futher ASGI implementation.

No functional changes. Get ready for an increase in file number.
