It is possible for an async thread to simply be deferred if not
specifically set to async. In which case, until the return value is
requested, the loop may simply wait.
By decoupling from std::thread, we can avoid the wait/sleep cycle in
checking the std::atomic completion variable. The std::future variables
are immediately returning without the additional atomic check cycle.
Fixes a crash when typing fast in the place footprint filter box.
Also adds a bunch more checking to GAL locking, including making
sure the same person unlocks as locked, and preventing piece-meal
calls (the RAII objects must be used).
This minimizes the thread usage, particularly during online actions such
as moving items and routing.
UpdateRatsnest: Minimized the number of atomics by utilizing future
promise. Avoided updating node-less nets. Node-less nets are common in
the dynamic ratsnest because the net vector is created from the board
nets by value but only populated with a subset. So the dynamic ratsnest
calculation always saw every net as dirty and spun up extra threads.
searchConnections: ParallelThreadCount is no longer lower bounded.
Small item counts are handled inline rather than with a separate thread.
When processing the selection filter, items were deselected before being
reselected after passing through the filter. This adjusts the logic to
only deselect those items that are filtered out.
Many operations on the selection involved getting an item by index or
dereference. The std::set needed to iterate from the beginning of the
set to find the item in its red-black tree. Using a deque that we keep
sorted, we get index access in O(1) and item search in O(lg N).
No dangling symbol for text items with a NO-CONNECT.
DanglingStateChanged doesn't work with dangling flag aggregators
(which return true if any child is dangling).
Then again, we don't actually use any of the aggregators anyway
so I removed them.

When importing an existing schematic into a sheet that was no remapped
to use the symbol library table, the user was given the option to ignore
the warning and proceed with the import. This would end up with all of
the imported symbol links being broke. In hindsight, this was a bad
idea so now the user cannot import schematics that have been remapped.

Some windows machines seem prone to sleeping for excessive times. When
called in the main thread, this may prevent the system from responding
to Windows 'Are you alive?' calls.
The compile flag -ffloat-store requires floating point values to be
stored in memory rather than in registers to prevent errors when two
numbers are compared that were stored in different locations.
This adds a test program which can be used to test the
parsing of a given KiCad PCB file. This interface is
useful for both manual or automated debugging of given
files, as well as providing an interface suitable for
fuzz-testing tools.
Also adds to the testing docs to detail how fuzzing can
be used.
Also moves some useful re-usable code from io-benchmark
to a new library qa_utils, which can contain code that
isn't need in the actual KiCad libs.
The decision to include the TTL library make KiCad a derivative work
under the terms of the AGPL version 3 or later license.
Add both the GPL3 and AGPL3 license text files and add a readme file
about the KiCad licensing. Contributing to KiCad still falls under
the GPL3+ license.
