* 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)

* Don't ignore set safe-linking settings
The previous code was testing the existance of the safe_lnk option
object, which always exists, and therefore was ignoring the actual
value of the option. Change the test to safe_lnk.value.
* Update pwndbg/glibc.py

GDB wraps stdout and doesn't proxy some functions through to the underlying TextIOWrapper. This causes pwnlib to error out when trying to detect terminal support.
By monkey patching the functions back onto the _GdbOutputFile object, we can use `pwnlib.term.text.red("hi")` to print colored text.
* Fix ansi color truncation in TUI windows
All remaining ansi escape codes after the substring of real characters weren't printed.
This caused some colors to linger over to the next line.
* Add two default TUI layouts
One including the sourcecode section and one without.
The allows to try the TUI quickly by selecting one of the layouts: `layout pwndbg` or `layout pwndbg_code`.
* Don't use \t tabs in context threads section
Horizontal scroll in TUI mode would jump around causing visual glitches. Use spaces instead.
* Add warning when section is in TUI layout but not in 'context-sections'
The section won't be updated automatically on stop.
* Update FEATURES docs including screenshot
* Don't create TUI windows when GDB is compiled without it
Don't stop pwndbg from loading on gdb without tui integration.
* Fix redraw of all windows after toggling TUI mode
When switching back to TUI mode, the contextoutput would be sent before a TUI window's `render` function was called. This caused some sections to be printed normally in the cmd window instead of being sent to their TUI window.
Keep a list of all open context TUI windows and redirect contextoutput for all of them once the first window is rerendered instead of waiting for them to be rendered too.
Also fix the _static_enabled class variable usage.
