* Remove {next,step}* tests from all commands tests
This optimizes CI test run; those commands are also kinda tested
elsewhere, maybe not fully, but let's leave it as it is for now...
* add total vs cumulative time for tests
* Use Zig for compiling for cross architecture tests.
* comments/typos
* Check if GDB supports crossarch targets, inline _start definition in assembly, add comments
* expand and add examples to pwndbg convenience functions
* update usage descriptions in _gen_*
* refactor out some common logic
* implement function doc generation
* change some mkdocs defaults around to be better for the general case
* generate function docs
* cleanup some examples, help, and quote escaping explanation
* move fsbase and gsbase definitions (and use decorator)
* cleanup signature for fsbase and gsbase
* autogen functions
* type annotation
* fix ida and binja descriptions
* rename arguments, reorder docs for `help function` and assert convention
* add missing imports
* use inspect.getdoc instead of directly accessing __doc__
for more consistency across python versions
* regen docs with getdoc()
* rewire exit and lint
* let users know about convenience functions through the `pwndbg` command
* sys.exit instead of exit
* splitting tests passed and skipped variable into two, solving issue #2485
* Fixing bugs in PR #2495
* jemalloc.py: remove unused Arena class (#2492)
* Fixes canary command when no canaries are there (#2496)
Fixes the following bug uncovered by our test_commands[canary] test suite:
```
(.venv) root@pwndbg:~/pwndbg# RUN_FLAKY=1 ./tests.sh 'test_commands' --pdb
Will run tests in serial and with Python debugger
ZIGPATH set to /root/pwndbg/.zig
make: Nothing to be done for 'all'.
pwndbg: loaded 173 pwndbg commands and 47 shell commands. Type pwndbg [--shell | --all] [filter] for a list.
pwndbg: created $rebase, $base, $bn_sym, $bn_var, $bn_eval, $ida GDB functions (can be used with print/break)

* Fix gdt command: require address argument (#2497)
Before this commit, the `gdt` command incorrectly did not require the `address` argument, while it was required.
Because of that, the command crashed like this:
```
pwndbg> gdt
'gdt': Decode X86-64 GDT entries at address
See also:
* https://wiki.osdev.org/Global_Descriptor_Table
* https://wiki.osdev.org/GDT_Tutorial
Note:
In 64-bit mode, the Base and Limit values are ignored, each descriptor covers the entire linear address space regardless of what they are set to.
Exception occurred: gdt: int() argument must be a string, a bytes-like object or a real number, not 'NoneType' (<class 'TypeError'>)
For more info invoke `set exception-verbose on` and rerun the command
or debug it by yourself with `set exception-debugger on`
```
* Add better handling for exceptions originating in execution controllers under LLDB (#2488)
* Fix try_free command: make addr argument required (#2499)
Fixes the following problem:
```
pwndbg> try_free
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'
> /root/pwndbg/pwndbg/commands/heap.py(1195)try_free()

* Fix ctxp command (#2498)
