Eliminate byte-typedef and use uint8_t in all their places instead. 
This change is made to (easily) be forward compatible with future C++
standards, in order to allow compiling the code with newer standards at
some point in the future.

* Removed the `using byte = uint8_t;` line from Common.h
* Mechanically change all uses of `byte` to `uint8_t`.

Tested with GCC 7.3 in C++11/14/17 modes :-)

6c3b48ddfc Added guards for unknown pragmas 
Removed push/pop if there was no change to the warnings *in the same
file* for a given compiler. This assumes the imported boost headers use
a warning stack themselves.

The pragmas don't seem to be required anymore, but were not removed to
mantain compatibility with older versions of the boost library.

Compiled with
- clang version 6.0.1 (tags/RELEASE_601/final)
- gcc (GCC) 8.1.1 20180531
 against:
- libboost 1.67.0-5

c603369a51 Change opcode generated by (panic) to INVALID 
EIP-141 ethereum/EIPs#141 has preserved 0xfe as an invalid opcode for aborting EVM execution. The EVM assembler supports this via the INVALID opcode.

The LLL "panic" expression used to generate a jump to an invalid location in order to abort EVM execution.  This change brings "panic" into line with EIP-141 by generating the INVALID opcode instead.
