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).
