[obv] gdbserver: Fix C++ build errors in tracepoint.c
Commit Message
These were introduced by 1cda1512689aabb36588a01370002632a0c8e560
and a13c46966d308297a1273e35ccc807a3912d573d . One is a simple
missing cast, the other is const usage on global function pointers
exported from IPA: in C++, consts are static, and thus won't be
exported from the DSO (the build error was because of non-applicable
visibility("default")).
gdb/gdbserver/ChangeLog:
* tracepoint.c (gdb_collect_ptr): Remove const qualifier.
(get_raw_reg_ptr): Likewise.
(get_trace_state_variable_value_ptr): Likewise.
(set_trace_state_variable_value_ptr): Likewise.
(initialize_tracepoint): Cast alloc_jump_pad_buffer result to
char *.

Thanks for noticing that. Here's the fix, pushed as obvious.
