The SEXPR class is a useful general-purpose S-Expression library
class and can (maybe) be used else where. It also should get
test coverage, as even if noone else uses it, it's critical for the
kicad2step exporter.
Also add some test coverage for some kicad2step routines. For now,
they're not useful outside kicad2step, but they are at least a useful
reference for S-Expression parsing.
This is not technically correct (the Boost dependency is introduced through
libcommon), but less invasive as it doesn't pull in libcommon on the linker
command line.
More recent Kicad_pcb files have quoted layer names (i.e.
strings, not symbols). The importer in K2S doesn't handle that,
so it chokes on elements like (layer "Edge.Cuts").

The addition of very small segments in OCE triggers sliver
removal/cleanup in the BREP generation that can get stuck in a very long
loop during STEP export of boards. These were introduced to ensure
closure of boards with small gaps that were too big for OCE to consider
joined.
Removing the small segments allows STEP export to proceed in a
reasonable time. This also decreases the default minimum gap size that
kicad2step uses to determine curve matching. This prevents mis-matching
small curves

STEP exporter keeps outline contiguous by storing the last point
coordinates and using them as the starting point for the next segment. It
might create a problem for arcs, as one of the arc end points may become
translated (changed to the last outline point), while the remaining
points (center and the other endpoint) are kept original. For large
deltas it renders an arc invalid, as it cannot pass through a modified
endpoint anymore.
To fix this, short segments are added to link the last outline point
with an arc endpoint, but only if the distance between the two is below
a certain threshold. This way the outline is kept contiguous and the arc
end point is unmodified, warranting its correctness.

The opencascade patch intrusively checked against libraries but broke
some build scripts. This restores the default cmake OCE behavior that was
changed by 2bab30d9a and makes the OpenCascade search truly secondary.

The file filter wild card was defined incorrectly causing the file picker
to not display *.stp and *.step file extensions. Change the wildcard per
wxFileDialog documentation.
Prevent the file extension from being forced to .stp even when the user
defined a different extension in the file picker.
Override TransferDataFromWindow to test for file existence and warn user
only once if a file overwrite can occur.
Minor STEP export dialog string and layout improvements.
Make kicad2step honor user's file extension rather than always setting it
to .stp.

Set BRL precision to 10 nanometers to prevent floating point round errors
from creating arcs that leave gaps in the board outlines. Note: it may
be prudent to make this setting 100 nanometers if there are gerber export
issues.
