* Downloadable content will now be indicating, in the log, whether it can be trusted with ✓ (validated) or ✗ (caution)
* Of course this validation only applies for files we know of, i.e. the downloadable content that existed at the time the DB was
created. So, if Syslinux 8.x gets released tomorrow and we put it on our server, you'll get an ✗ regardless of its integrity.
* Closes#758
* Use the commonly used function names for SHA-256 (Sigma, etc.)
* Use the same xxx_write for all, and avoid unwarranted memcpy
* Remove the bitcount
* Use nested ROR() speedup
* That's more like it! When compiled in 64-bit we get about the same speed as 7-zip
(slower when 32-bit, but shhh, or people will ask for a 64-bit version of Rufus...)
* Looks like what was holding us back was the sha256_write() from Brad Conte's
* Also fix WDK compilation and harmonize the BE->LE conversions
* SetChecksumAffinity() now spreads the affinity evenly between cores
* Also increase the read buffer size to help with performance
* At this stage, the only limiting factor regarding performance seems
to be the speed of the SHA-256 algorithm...
* Also update Bled to latest, as well as build scripts
* Note: Considering that Visual Studio 2015 is both freely and legally
available for anyone who wants to use it to compile Rufus, starting
with this commit, I will NOT be supporting any other version of Visual
Studio but 2015.
