Currently, the ArmVirtPkg platforms built with the Intel BDS fail
to signal the end-of-DXE event 'gEfiEndOfDxeEventGroupGuid' when
entering the BDS phase, which results in some loss of functionality,
i.e., variable reclaim in the VariableDxe drivers, and the splitting
of the memory regions that is part of the recently added UEFI 2.5
properties table feature.
As discussed on the edk2-devel mailing list here:
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109
it is up to the platform BDS to signal that event, since there may be
platform specific ordering constraints with respect to the signalling
of the event that are difficult to honor at the generic level.
So add the SignalEvent () call to PlatformBdsInit () of ArmVirtPkg's
PlatformBdsLib implementation for the Intel BDS.

This is a followup to r17554 ("ArmVirtPkg: increase memory
preallocations to reduce region count") that increases the sizes
of the preallocated regions to account for the footprint of the
crypto and authentication libraries. This is only done if secure
boot is enabled at build time, to prevent imposing a larger minimum
RAM size on non-secure builds.

Both files originate from ArmPlatformPkg.
The copyright notices at the top of "License.txt" have been refreshed as
follows:
- I grepped ArmVirtPkg for "copyright", case-insensitively
- for each copyright holder company, I unified the intervals to the
strictest superset (no absent year was introduced in this process)
- I listed the copyright notices in decreasing order of last contribution
year.
- When a "last contribution year" was shared by several notices, I sorted
those between each other in descending "first contribution year" order.

This updates the sizes of the preallocated regions so that the number
of distinct regions that exists is minimal at the time we exit boot
services.
For a typical run of the ArmVirtQemu platform, we get the following
utilization numbers:
Reserved : 4 Pages (16,384 Bytes)
LoaderCode: 210 Pages (860,160 Bytes)
LoaderData: 0 Pages (0 Bytes)
BS_Code : 355 Pages (1,454,080 Bytes)
BS_Data : 6,807 Pages (27,881,472 Bytes)
RT_Code : 112 Pages (458,752 Bytes)
RT_Data : 288 Pages (1,179,648 Bytes)
ACPI_Recl : 32 Pages (131,072 Bytes)
ACPI_NVS : 0 Pages (0 Bytes)
MMIO : 16,385 Pages (67,112,960 Bytes)
MMIO_Port : 0 Pages (0 Bytes)
PalCode : 0 Pages (0 Bytes)
Available : 123,264 Pages (504,889,344 Bytes)
--------------
Total Memory: 511 MB (536,854,528 Bytes)
Strangely enough, the allocation count of 20,000 pages for BS_Data
does not result in those regions being merged. For BS_Code, RT_Code
and RT_Data, the increased preallocation results in the following
reduction in the number of regions.
