2037b837f8 sbtools: convert crypto to libtomcrypt.
Replace the use of crypto++ with tomcrypt, which is much smaller and C.
This gets rid of various build issues for systems that don't ship
crypo++ (i.e. everything except Linux.)

815b289cb3 imxtools: Replace use of "byte" with its underlying uint8_t.
libtomcrypt uses a macro "byte" which conflicts with this type. Since
the underlying type is uint8_t and there's no real benefit from using a
custom type use the actual underlying type.

a5f228eee2 rbutil: fix windows cross compile (via M cross environment)
This fixes a couple of issues when cross-compiling for windows:
 - lib builds (i.e. mks5lboot) were overriding the cross CC/CXX with the
   native CC, producing incompatible binaries.
 - Qt made the accessibility plugin part of the core library, so we no
   longer need to import it.

759a78e5df imxtools/sbtools: switch SHA1 implementation to Crypto++
The current implementation was custom and super slow. Since we use Crypto++
anyway, we might as well get use a good implementation.

8b3f5a8ad7 imxtools/sbtools: switch AES implementation to Crypto++
Instead of having our own copy of the AES code, use a good library to do that.
Crypto++ is well-maintained, supports a lot of ciphers, works on many OSes, and
is optimized for many architectures.

2b20026dd7 imxtools/sbtools: rework cryptography
It was a mess, a mix of crypto_* and cbc_mac calls. I made everything call crypto
functions, and also separate key setup from cryptographic operations, this will
be useful to speed up the code in the upcoming commits. Drop support for "usbotp"
key, since the crypto code for that was never mainlined and we can always get the
keys from a device as long as we have code execution (using the DCP debug registers).

b05b762ed4 sbtools: add brute force option for sb1 in sbtoelf
After some reverse engineering, it appears that the keys of the
sb1 format are very weak: the 128 bytes are generated from the
laserfuse words 4,5 and 6 but in a weird manner: 4 and 5 are
simply ORed and 6 is only half used (somehow), making it "only" a
48 bit word to find.

4e95b72ecb sbtools: add support for the stmp36xx format
The STMP36xx series also uses .sb files but with a different
format. The main differences are the encryption and the lack of
sections, making it basically a list of commands: fill, load,
call, jump, switch mode, set sdram settings. Currently only the
sbtoelf has support for the sb1 and can only dump the list of
commands. Actual support for elf creation will come later.
