===================
Backwards incompatible changes:
- `spinta push` command is now unified with other commands and works like
this `spinta push manifest1 manifest2 target`. Target configuration is moved
to XDG compatible credentials configuration, state is now saved in a XDG
directory too, by default. `-r` was replaced with `--credentials`, but by
default credentials are looked in `~/.config/spinta/credentials` so there is
no need to specify it. `-c` flag is also no longer exists, you can add
client to target like this `clienttarget`, if client is not specified it
will be read from credentials file.
- Now configuration and data files are stored in a XDG Base Directory
Specification compatible directories, by default, but can be overridden via
main config file, environment variables or command line arguments.
Performance improvements:
- Migrated from Earley to LALR(1) parser algorithm and this made formula
parser 10 times faster, doing write operations involving `_where`, things
should be about 3-5 times faster. Whole test suite after this because 20%
faster.
- Moved select list handling out of rows loops and this made lists of objects
about 5 times faster.
- Enabled server-side cursors for getall actions, now memory consumption is
always constant even when downloading large amounts of data.
- Fix few bugs in access logging, because of these bugs whole result set was
consumed at once and stored in memory. This cause delays, when starting to
download data and also used a lot of memory.
