- In vstruct/defs/ihex.py getMemoryMaps, there is not a check for
IHEX_REC_STARTLINADDR. The patch adds a check for this record type and
skips over the chunk, similarly to IHEX_REC_STARTSEG.
* sped up vsEmit() of ihex and srec file formats
* updated generator comprehension to be more efficient per suggestion

* Migrate away from deprecated `assertRaisesRegexp`
In Python 3.12 `assertRaisesRegexp` will no longer work. Replace it with
`assertRaisesRegex`.
* Migrate deprecated threading.currentThread
* Migrate from deprecated `threading.Thread.setDaemon`
* auto-build getArchModules() using getArchModule()
refactor getArchModule() to load from a set of dictionaries (instead of manually importing and loading each arch module based on manual matching of the arch string name)
clean up arch_by_name to only include a direct 1-to-1 mapping. probably should autogenerate this from arch_names
creation of getArchNames() to return a dictionary with only the correctly loaded architectures (for use in things like the Viv Context Menu)
* fix older ELF parsing bug (robustness in the calculation of DYNAMICS DynSyms table)
* bugfix: strsz
* tweak
* clarification and tweak
* delete commented old code
* commentary
* integer division, please.
* removed comments which are half-truths
* architectures transformation to a dict of dicts
* implementing the module loader as a separate function.
storing full path to the envi module libraries, and the ArchitectureModule as a separate field in the dict.

* tests for vivisect.reports
* PE.carve bytes/string IO fix
* lots of fixes to the intel emulators per the lockstepper test which only runs on windows.
* utilitize some common hex functionality
* clean up the emulators a bit. tried to use safemem to fix the bug, but that didn't work as intended.
* ton of cleanup and test cleanup. and also emulator fix
* found the edge case
* Make the dirs on a save just in case
* fix issue with v_zwstr in vstruct parsing and cleanup
* Bunch of little fixups from division fixes for py2/3 stuff, a set of new intel instructions (from decoding all the way up to symboliks), to PE loading
* Docstring updates, more unittests for vstruct, extension fix, memcanvas fix for certain edge cases. Overall: incorporating feedback from @willi and @atlas
* custom log level
* envi config encoding per @willi, getting memoryview hotkeys working again for the same reason mouse was broken
Massive cutover to python3 (baseline is 3.9.1, but is also tested/working on 3.7.x). This merge is a breaking change for any downstream consumers, as the python 2->3 strings/bytes change is central. Most APIs should still work roughly as intended, as I didn't majorly re-organize the codebase, so most APIs live where they lived before. But a changelog/migration guide will be included in the next PR for this.
This PR will constitute most if not all of the v1.0.0 release that is forthcoming soon.
