* Add support to use heap commands without debug symbols
* Fix a possible bugs when getting heap boundaries via heuristic
See https://github.com/pwndbg/pwndbg/pull/1029#issuecomment-1189841299
* Fix typo causing issues in `c_malloc_par_2_25`
See https://github.com/pwndbg/pwndbg/pull/1029#issuecomment-1189841299
* Fix a bug for `tcache_perthread_struct` and refactor some codes in `structs.py`
* The bug: `tcache_perthread_struct` for GLIBC < 2.30 is using `char` instead of `uint16_t` for `counts` field
* Fix some bugs about handling `thread_arena` and `tcache` with multithreaded
* Re-initialize the heap when the process stop or the file changed
By doing this, we can attach to another architecture in GDB without any bugs.
* Add guard code for unsupported architectures
* Support heuristic for arm and aarch64
Note: thread_arena and thread_cache for arm still can not work
* Update .pylintrc
* Ignore `import-error` error for `import gdb`
* Ignore `no-member` error for `pwndbg.typeinfo.*`, because most of its members are dynamically generated.
* Ignore `protected-access` warning for `_fields_`, `_type_`, `_length_`, because ctypes don't have other ways to access them.
* Refactor some code and comment to fit pep8 and lint check
* Add a feature to enable users set symbol addresses manually
For example, by using `set main_arena 0xdeadbeaf`, pwndbg will try to find main_arena at 0xdeadbeaf when using heuristic
* Use `__errno_location` to find TLS base for arm
By doing this, we can get `thread_arena` and `tcache` address
* Block other thread before `__errno_location()`
* Fix a bug for arm32 and a typo-caused bug
* Some wrong field names inside `c_heap_info` may cause some bugs in the future if we want to access it
* `pad` size of `heap_info` for arm32 is 0 byte, only i386 is 8 bytes, so I fixed it in a hard-coded way temporary
* Fix#1044 related issues
* Refactor the code about heap related config
* Use `int(address_str, 0)` to auto determine the format (https://github.com/pwndbg/pwndbg/pull/1029#discussion_r939569382)
* Use `OnlyWithResolvedHeapSyms` instead of `OnlyWithLibcDebugSyms` (https://github.com/pwndbg/pwndbg/pull/1029#discussion_r939568687)
* Use `resolve-heap-via-heuristic` instead of `resolve-via-heuristic` (https://github.com/pwndbg/pwndbg/pull/1029#discussion_r939569076)
* Update the description of `resolve-heap-via-heuristic` config (https://github.com/pwndbg/pwndbg/pull/1029#discussion_r939569069)
* Move heap related config into `heap` scope, and add a new command, `heap_config`, to show the config in that scope (https://github.com/pwndbg/pwndbg/pull/1029#discussion_r939569260)
* Refactor code about the config of heap related symbols
* Fix the logic when thread_arena is not found
* Use errno trick as a fallback for i386 and x86-64
* Update pwndbg/heap/ptmalloc.py
