Technically Arch Linux ARM is a separate distro from the x86_64 Arch Linux, but it uses pcaman and the same package names. So it installs just fine, just needs to be detected properly.
* feature: Add `killthreads` command (closes#1580)
This command allows the user to quickly kill multiple threads by
specyfying their ids as arguments to this command. It also supports
the `--all` flag, which will kill overy thread except the currently
selected one. This is useful for use with the `checkpoint` command.
The killing is done by calling `pthread_exit(0)`.
* fix: try fixing building test binaries by enabling -lpthread
* fix: remove error message check when calling pthread_exit
Removed the message check, because the error messages difffer between
versions of GDB.
* fix: Improve UX of the killthreads command
Add an extended description of the command, some validation on the thread IDs
and suppress GDB output.
* fix: lint
* fix: put the multiline help text in the correct place
* tests: fix test failing due to a race condition when running in parrallel to other tests
Replaced asserts with loops which wait for a cundition to be met, so that the tests doesn't fail due to scheduling issues.
* tests: add more fixes for race conditions in test_killthreads
* fix: lint
* Update pwndbg/commands/killthreads.py
* tests: Wait for exactly three threads

Now the installation process contains the following steps:
1. Check for any line with source <gdbinit.py> before installation
2. If any, ask the user if they want to proceed
3. After the installation, comment out old source <gdbinit.py> lines if any and add a new source <gdbinit.py> line.
A check for presence of the line set debuginfod enabled on is also added to avoid being appended repeatedly.

It seems this function is redundant. If you do:
```
gdbserver 0.0.0.0:1234 ./a.out
```
on a local machine and then do `gdb ./a.out --ex 'target remote :1234'`
the `_add_main_symbol_to_exe` will kick off and run its
`add-symbol-file` command to add the symbols from the binary. However,
the GDB already loaded the binary symbols and so we will do it for the
second time. As a result, we get something like this:
```
pwndbg> info symbol main
main in section .text of /pwndbg/bug/vaccine
main in section .text of /pwndbg/bug/vaccine
```
This function has been in Pwndbg since always and I am not sure why we
needed it. Perhaps an old GDB did not download the binary from the
remote target, but since now GDB does this automagically, this function
seems redundant.
Just for the sake of documenting it, here is how a symbol appears if you
connect to a remote target on a different machine without Pwndbg (the
GDB downloads the binary itself and loads its symbols):
```
(gdb) p main
$1 = {<text variable, no debug info>} 0x55555555466a <main>
(gdb) info symbol main
main in section .text of target:/home/dc/a.out
```
This commit adds a fix and tests for #1600 and #752.
* https://github.com/pwndbg/pwndbg/issues/1600
* https://github.com/pwndbg/pwndbg/issues/752
Generally, for an example like this:
```cpp
struct A {
void foo(int, int) { };
};
int main() {
A a;
a.foo(1, 1);
}
```
The output for `info symbol <address of A::foo>` returns:
```
'A::foo(int, int) [clone.isra.0] + 3 in section .text of /root/pwndbg/tests/gdb-tests/tests/binaries/a.out\n'
```
We then used this code to parse this:
```py
# Expected format looks like this:
# main in section .text of /bin/bash
# main + 3 in section .text of /bin/bash
# system + 1 in section .text of /lib/x86_64-linux-gnu/libc.so.6
# No symbol matches system-1.
a, b, c, _ = result.split(maxsplit=3)
if b == "+":
return "%s+%s" % (a, c)
if b == "in":
return a
return ""
```
The `result.split(maxsplit=3)` here splitted the string to:
```py
['A::foo(int,',
'int)',
'[clone.isra.0] + 3 in section .text of /root/pwndbg/tests/gdb-tests/tests/binaries/a.out\n']
```
And since `b` was not `"+"` or `"in"` we eventually returned an empty
string instead of the `A::foo(int, int)` which would be expected here.
* Fix the bug when using LD_PRELOAD to load libc
The heap heuristics will try to find `libc.so.6` in the output of `info sharedlibrary`, but if we load libc with `LD_PRELOAD`, the filename of the libc might not be `libc.so.6`.
* Add test for `glibc.get_libc_filename_from_info_sharedlibrary`
