Florian Hofhammer	0443c203c4	plugins: add missing callbacks to version history The discontinuity and system call filter callbacks were not reflected in the versioning comments before. The callbacks have been introduced in `aac73d85d2` and `5ed628d1d3`, respectively.

Florian Hofhammer	3ebd871cbd	plugins: add read-only property for registers Some registers should be marked as read-only from a plugin API perspective, as writing to them via qemu_plugin_write_register has no effect. This includes the program counter, and we expose this fact to the plugins with this patch.

Florian Hofhammer	4f55cd7801	plugins: add PC diversion API function This patch adds a plugin API function that allows diverting the program counter during execution. A potential use case for this functionality is to skip over parts of the code, e.g., by hooking into a specific instruction and setting the PC to the next instruction in the callback.

Florian Hofhammer	d16ffa4244	plugins: add flag to specify whether PC is rw In addition to the flags specifying whether general-purpose registers are read-write (rw) during a plugin callback, we add an additional flag explicitly stating whether the PC is writable. This is in preparation of a patch that allows to explicitly set the PC to divert control flow from within a plugin callback, which is currently not possible.

Pierrick Bouvier	cab15547f1	plugins: move qemu-plugin.h to include/plugins/ This change has two benefits: - ensure plugins can't include anything else from QEMU than plugins API - when compiling a C++ module, solves the header conflict with iostream header that includes transitively the wrong ctype.h, which already exists in include/qemu. By Hyrum's law, there was already one usage of other headers with mem plugin, which has been eliminated in previous commit.
