This commit upgrades glibc shared library stub-creating code to use the
new abilists file which is generated by the new glibc-abi-tool project:
https://github.com/ziglang/glibc-abi-tool/
The abilists file is different in these ways:
* It additionally encodes whether a symbol is a function or an object,
and if it is an object, it additionally encodes the size in bytes.
* It additionally encodes migrations of symbols from one library to
another between glibc versions.
* It is binary data instead of ascii.
* It is one file instead of three.
* It is 165 KB instead of 200 KB.
This solves three bugs:
Fixes#7667Fixes#8714Fixes#8896
