This allows us to have reproducible builds while keeping the
DWARF loading phase in parallel, achieving a noticeable speedup as
showed in the commit log messages.

v2: Don't delete the CUs after encoding BTF for them, we may still have
still references to them from the BTF encoder, as noticed by Alan
Maguire.
Arnaldo Carvalho de Melo (12):
core: Allow asking for a reproducible build
pahole: Disable BTF multithreaded encoded when doing reproducible
builds
dwarf_loader: Separate creating the cu/dcu pair from processing it
dwarf_loader: Introduce dwarf_cus__process_cu()
dwarf_loader: Create the cu/dcu pair in dwarf_cus__nextcu()
dwarf_loader: Remove unused 'thr_data' arg from
dwarf_cus__create_and_process_cu()
core: Add unlocked cus__add() variant
core: Add cus__remove(), counterpart of cus__add()
dwarf_loader: Add the cu to the cus list early, remove on LSK_DELETE
core/dwarf_loader: Add functions to set state of CU processing
pahole: Encode BTF serially in a reproducible build
tests: Add a BTF reproducible generation test
