Commit Message

Cache output of `asm()` (#2358)

* Cache output of `asm()`

To speed up repeated runs of an exploit, cache the assembled output.

Use a sha1 hash of the shellcode as well as relevant context values
like `context.arch` and `context.bits` to see if the exact same
shellcode was assembled for the same context before.

Fixes #2312

* Return path to cache file if `not extract`

* Update CHANGELOG

* Create temporary copy of cached file

* Add debug log about using the cache

* Include full assembler and linker commandlines in hash

This should catch any changes across pwntools updates and system environment changes.

* Include pwntools version in hash
