Subject: [PATCH] libelf: Replace list of elf_getdata_rawchunk results with a
tree
elf_getdata_rawchunks did a linear search to see if a chunk was
already fetched. Replace this list with a binary search tree to make
lookup faster when a lot of Elf_Data_Chunk were created.
* libelf/libelfP.h (Elf_Data_Chunk): Remove next field.
(struct Elf): Change the rawchunks type from Elf_Data_Chunk *
to void *.
* elf_getdata_rawchunk.c (chunk_compare): New static function.
(elf_getdata_rawchunk): Use tsearch instead of a manual linked
list.
* elf_end.c (free_chunk): New static function.
(elf_end): Call tdestroy instead of walking linked list.

Subject: [PATCH] elfcompress: Don't compress if section already compressed
unless forced
Before commit a5b07cdf9 "support ZSTD compression algorithm"
elfcompress would not try to compress a section if it already
had the requested compression type (or was already uncompressed)
unless the --force flag was given. An else if construct was changed
to an if in the commit causing elfcompress to warn (in verbose mode)
but then still try to (re)compress the section.
Add an explicit check so if nothing needs (un)compressing, the file
isn't changed.
The diff looks large, but git diff -b -w is just:
