When we moved to argparse command parsing we introduced `gdb_sloppy_parse` which wasn't perfect: e.g. for `gdb.parse_and_eval("__libc_start_main")` would return a `gdb.Value()` whose `.type.name` was `long long`.
As a result when code that used `gdb_sloppy_parse` then casted the result to `int(gdb_value)` it crashed because for some reason GDB errored.
This commit fixes the issues related to it by adding `AddressExpr` and `HexOrAddressExpr` functions.
It also adds tests for some of the windbg compatibility commands and fixes some nifty details here and there.
* Tests launcher: show passed and failed count
* Build nearpc, emulate, u, pdisass test binaries
* Add tests for emulate, nearpc, pdisass, u
* Refactored disasm and emulator
* Fix nearpc following jumps w/o emulation
* Prevent tests from calling start_binary twice
* Add test for emulate_disasm_loop
* Fix isort
* Add nasm to travis install
* Add --eval-command quit to tests invocation
This should prevent travis from staying in gdb/stalled build when something fails in weird way (like a file is missing)
```

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.
