New features:

Support for DWARF 5 was added.
Object.from_bytes_() was added. It creates an object from its binary representation.
Object.to_bytes_() was added. It gets the binary representation of an object.
Helpers for Linux kernel NUMA node masks were added (drgn.helpers.linux.nodemask).
Helpers for Linux kernel bit operations were added (drgn.helpers.linux.bitops).
Helpers for getting network devices by name or interface index were added (drgn.helpers.linux.net.netdev_get_by_{index,name}()).
drgn.helpers.linux.sched.task_state_to_char() was updated for Linux v5.14.

Fixes:

A bug when translating values from little-endian to big-endian was fixed.
A workaround for a bug in elfutils < 0.177 was (re)added. The bug causes stdin to be closed and another file descriptor to be leaked when targeting a userspace core dump.
Support for the kdump format was fixed (it was broken in v0.0.12 and v0.0.13).
A potential buffer overread caused by DWARF information with an invalid DW_AT_strp value was fixed.
A potential buffer overread caused by DWARF information with an invalid 64-bit size on a 32-bit system was fixed.
Missing support for the DWARF DW_FORM_block encoding was added.
Support for DW_FORM_ref_addr in DWARF 2 files was fixed to use the correct size.
"Non-canonical" LEB128 values are now handled correctly.
Stack trace object lookups and source location lookups were fixed for files with incomplete .debug_aranges information (e.g., the Linux kernel when compiled by Clang).
drgn.helpers.linux.cpumask.for_each_cpu() was fixed to not read out of bounds in kernels configured with CONFIG_CPUMASK_OFFSTACK (e.g., Fedora kernels).
