* Only run arch for testing
* Remove outdated arch repo
* Actually build the docker image
* Do not include site packages in sys.path
* Ignore `.relr.dyn` section; skip lines w/o spaces
Newer binaries can contain a `.relr.dyn` section to compress `R_X86_64_RELATIVE` relocation entries.
These binaries can be found for example on archlinux but also on Debian 12 for example.
`readelf` prints the content of the section similarly to this:
```
Relocation section '.relr.dyn' at offset 0x25220 contains 35 entries:
1198 offsets
00000000001ce8d0
00000000001ce8e0
```
Compared to `00000000001d2000 0000000000000025 R_X86_64_IRELATIVE 9f330` for
`.rela.plt`.
Pwndbg now chokes on the new format because it expects a space seperator where there is none.
It might be, that this is actually an upstream problem with binutils, because llvm-readelf prints this:
```
Relocation section '.relr.dyn' at offset 0x25220 contains 1198 entries:
Offset Info Type Symbol's Value Symbol's Name
00000000001ce8d0 0000000000000008 R_X86_64_RELATIVE
00000000001ce8e0 0000000000000008 R_X86_64_RELATIVE
```
Nevertheless, we aren't actually interested in `R_X86_64_RELATIVE` relocations so I guess it's fine to
just skip all lines that contain no spaces at all.
`.relr.dyn` can only containt `R_X86_64_RELATIVE` relocations as far as I understand

* Accept Full RELRO in test
Archlinux has libc and ld with Full RELRO.
We now just accept Partial and Full RELRO.
* Do not copy binaries from host to docker
The `Dockerfile` copies the whole pwndbg folder to the image.
If we have built binaries on the host before, these binaries will contain references to
the host system and *copied* to the image.
If we now run `context code` (inside docker) to have a look at the source code this will
fail, because we will try to refer to a path on the host system.
* Do not use loop index after loop
Do not use loop index after the loop. The tests assumed that the loop in line 186
would run at least once, thereby *resetting* `i` to zero. If we never enter the
loop, `i` will *continue* to have the value it had at the end of line 172.
This will cause the test to fail in mysterious ways because `i` is now not reset
to zero but still has the value `31` for example.
The solution is to never use `i` outside of a loop.
* Re-enable archlinux and temporarily disabled ones
* Change setup.sh to create & use Python virtualenv
The `setup.sh` script now creates a `.venv` directory during execution and installs all dependencies into that directory. Then, `gdbinit.py` will adds the proper `site-packages` directory as the first item of `sys.path`.
Fixes#1634.
* Fix plt and gotplt commands
* Add plt gotplt commands tests
* Fix got and plt commands and test them
* Revert accidental change
* Extend system path
* Hopefully fix PATH problems once and for all?
* fix import
* remove redundant part
* gdbinit.py: fix message when locales are wrong
Apparently the suggested solution is not great:
```

Your encoding (ANSI_X3.4-1968) is different than UTF-8. pwndbg might not work properly.
You might try launching gdb with:
LC_ALL=en_US.UTF-8 PYTHONIOENCODING=UTF-8 gdb
Make sure that en_US.UTF-8 is activated in /etc/locale.gen and you called locale-gen

* fix lint
* add patch command
This commit adds the `patch`, `patch_list` and `patch_revert` commands
and adds the `pwntools==4.8.0` as Pwndbg dependency.
The current implementation could be further improved by:
- adding tests :)
- maybe moving `patch_list` and `patch_revert` to `patch --list` and
`patch --revert` flags?
- better handling of incorrect args/pwnlib exceptions
* lint
* remove py2 coding notations from files
* remove six package use and replace with proper py3 code
* remove py2 futures use
* replace unicode string literals with string literals
* remove python2 urlparse import in favor of python3 urllib.parse
* keep ida_script in py2 version
* remove hashbang python lines as the files are never ran directly
