88a09dd13a cscore: Handle USB camera integer menus (#1561) 
The Pi Camera is one of these.  Previously, integers were just being
cast to a string instead of formatted as a string.

6105873cbe Provide alternate device paths info for USB cameras (#1519) 
This is primarily for use on Linux to get by-id or by-path device names.

This information is now part of UsbCameraInfo.

A new entry point was added to UsbCamera to get that camera's UsbCameraInfo.

The alternate paths are also returned in EnumerateUsbCameras.

c405188052 Fix directory iterators not working correctly (#1454) 
The size of the directory_entry was different between translation units.
This was caused by the FILE_OFFSET_BITS macro when building wpiutil.
Removing that fixes the issue.
Should fix NavX USB issues.

ecd376be4c Export C functions from JNI statically linked library (#1425) 
The JNI libraries are useful from other tools, so they should contain the C functions.

9bc998f4b0 cscore: Add JSON for source settings (#1423) 
This allows save and restore of camera settings.  The restore is a bit
smarter than the save.

* Fix mime types in mjpeg server

* wpiutil: WPI_LOG: Make sure level is an unsigned int

global singleton destruction.

e27d6d7bb8 cscore: Change impl to only one singleton (#1398) 
This avoids a number of shutdown use-after-free races by controlling the
destruction order.  It also is a prerequisite to making the internal
interfaces mockable for unit testing.

0a0d9245e2 cscore: Add connection strategy to sources (#1252) 
By default, sources automatically manage their connection based on whether
any sinks are connected.  This change allows the user to keep a connection
open or force it closed regardless of the number of connected sinks.

0e9172f9a7 Fix many errorprone warnings (#1247) 
This fixes two real bugs:
- TimedRobot had a m_period that was hiding the IterativeRobotBase m_period
  and was not getting initialized.
- PDPSim was swapping two parameters to getCurrent()

00c2cd7dab Improve JNI loading efficiency (#1224) 
A hash is stored for each native library with the name libraryName.hash.
If the library is not found on the system search path, it is extracted to a cache directory.
Extracted libraries are named with the hash appended, so the library will not be
re-extracted if one with the same hash already exists.

Hashing without the hash file requires double traversing if the file is not in the cache,
but it is still faster than creating a new file in most cases.  This won't be needed
after opencv is updated to provide a hash as well.

c9a75a119a cscore: Support multiple levels of JPEG compression (#1223) 
This allows two streams with different compression levels, and also allows
a stream to receive a different compression level than provided by a JPEG
camera (decompress and recompress).

04ee8dbe79 UsbCamera: In JPEG mode, get size from image instead of mode (#1222) 
Some cameras will accept a different resolution as the mode but then provide
JPEG images of a different size.  Trust the JPEG image size if available.

This also validates the JPEG image is actually JPEG.
