This feature only works with server implementations that have ReverseStep
and ReverseContinue enabled, such as rr. The official gdbserver doesn't support it.

Last release (4.1.0) did compile it by default, but the build requires
internet access to download the repositories. For now, since the feature
is anyway very experimental, we disable it at compile time so that
distributions can just compile their packages without internet access.
In the future we may want to use submodules or augment the release
tarball to include the tree-sitter and radare2-shell-parser archives.
Most servers/clients should have xml support by now so it should behave
like `dp` in any other debugger. vFile is the only way to get detailed pid info unfortunately.
Before we didn't check if a virtual address read/write would go through a page boundary. This fixes it.
Also do some formatting and re-enable some useful error messages
Previously, windbg_break would freeze waiting on a lock instead of breaking,
taks other than wait weren't breakable and read regs would freeze the
process while waiting for a mutex.
Since r2 doesn't support set/get to large/vector registers (it will still work
when printing gdb's registers with dr/drt or restoring the registers
with reverse stepping), there's a possible issue that the user will get
lots of prints of "r_reg_[get/set]_value: Bit size 128 not supported"
when running various debug commands that use those functions. This fix
simply moves those registers away from gpr to avoid those prints while
still being able to view/restore the registers.
Writing registers with gdbr worked with single registers because
reg_next_diff started at delta 0 and only had to run the diff once for
the single register that was changed. When running reverse
stepping/continue, multiple registers are changed at once so
r_reg_next_diff would fail every time due to incorrect offset calculation.
The new r_reg_next_diff also support different register sizes to restore
all registers correctly.
The endianity swapping part from reg_write isn't needed since the arena
is the return value of 'g' which is already in the correct target byte
order (see: https://sourceware.org/gdb/onlinedocs/gdb/Packets.html#read-registers-packet)
The socket object was free'd without closing the fd. In the following
gdbr_connect attempts, tcp's connect would freeze on a valid socket since
connection based protocol sockets may successfully connect only once,
any connections beyond that are undefined behavior.
Previously, write_registers sent a partial string instead of the
correct register format which specifies that each byte should be
represented by two hex digits.
The previous gdbr implementation didn't allow interrupting background
tasks with &b since send_vcon wasn't properly configured with the cons
api. In addition to that, gdbserver doesn't support processing multiple
commands at the same time, resulting in undefined behavior once cons
were set up for vcont.
This commit adds the relevant cons api and solves the concurrency issues
by adding locks on all socket related logic.
* tree-sitter-integration: support tmp-seek, arged, and interpret commands
* Make meson automatically download tree-sitter and radare2-shell-parser grammar
* Add tree-sitter/radare2-shell-parser directories in gitignore
* Add Support for tree-sitter in acr/makefile
* Just use one script to download 3rd party repositories in shlr
* Use cfg.newshell
The user was interrupted during continue and switched to a different
thread since DebugBreakProcess creates a thread that triggers a breakpoint.
With these changes the DebugBreak thread is recorded to skip the breakpoint
event afterwards.
* Added ba2 so that the gdbserver backend connects correctly
* Fixes to remote gdb register writes:
1. Byte order is target-defined. Use cfg.bigendian for now. Possibly get it from target later?
2. Register number should be hexadecimal.
* Reimplement r_buf_fread/fwrite
* Add slice buffer and introduce readonly field
* Do nothing if size is 0
* Prevents an overflow when 8 is subtracted from size.
* Fix ragg2 when patching outside currently existing buffer
* Implement r_mem_mmap_resize for systems where mremap is not defined
* r_buf_buffer can be called with no size arg as well
* Use size_t instead of ut64
