Having thread pool as its own singleton in the library meant that each
kiface had its own threadpool, leading to many multiples of the threads
being started. Placing a singleton class in PGM_BASE ensures that all
kifaces use the same thread pool.
The singleton class can be extended to provide single instance
guarantee for any element across kifaces
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
GetCopperLayerStackMaxId() replaces GetCopperLayerCount()*2 and is more
understandable in code where the max allowed PCB_LAYER_ID value is needed.
Removed also a dead code related to GetCopperLayerCount() < 2, broken and not
allowed in Kicad.
CHANGED: PCB file format now supports saving/loading complex padstacks
CHANGED: PTH pads are now rendered per copper layer in the copper color;
the PTH pad color is no longer used.
ADDED: support for importing complex pad stacks from Altium PCBs
Enforce padstack-aware access to pad properties across KiCad

F_Cu = 0
B_Cu = 2
Remaining internal copper layers are even and incrementing
Non-copper layers are odd and incrementing.
This means that we can no longer do things like:
for( PCB_LAYER_ID layer = F_Cu; layer <= B_Cu; ++layer)
Instead, we have the class LAYER_RANGE:
for( PCB_LAYER_ID layer : LAYER_RANGE( F_Cu, B_Cu) )
Similarly, gt/lt tests should not refer to the integer value of the
layer. We have functions such as IsCopperLayer to test whether a layer
is copper or not.
When using the connectivity RTree, the third dimension is layer, so we
provide B_Cu with the special INT_MAX value, ensuring that elements
between F_Cu and B_Cu will be identified. There is a new, special
function GetBoardLayer() for interfacing with CN_ITEMS
Similarly, PNS layers remain unchanged and sequential. A set of
interface functions is provided to map PNS layers to Board layers and
back. This allows the PNS_LAYER_RANGE to function as expected
SHA256 is fine for one-offs but for large libraries where we might be
running the hash on hundreds of files, the speed difference is
appreciable. We don't require crytographic hashing, just a check that
the original file hasn't been corrupted so Murmur3 satisfies our basic
requirement.
In some cases, when modifying a pad (SMD -> NPTH from properties panel, one
can generate a NPTH pad with a zero sized hole. Pcbnew can crash with such a pad,
especially if the 3D viewer is shown during modification.

Schematics, symbols, boards and footprints all get the ability to store
files inside their file structures. File lookups now have a
kicad-embed:// URI to allow various parts of KiCad to refer to files
stored in this manner.
kicad-embed://datasheet.pdf references the file named "datasheet.pdf"
embedded in the document. Embeds are allowed in schematics, boards,
symbols and footprints. Currently supported embeddings are Datasheets,
3D Models and drawingsheets

This prevents crashes when trying to re-evaluate
during destruction, etc. and is a cleaner solution
than trying to keep a flag updated.
It should also be a performance win for very large
documents.
Also implements proper threadlocking for the cache.

Required for net inspector otherwise composite operations (such
as undo / redo, and length tuning) can result in multiple add /
remove events firing which results in inconsistent length state.
