- Use the same mechanism (debug_map) in Pal/Linux and Pal/Linux-SGX. Previously, Pal/Linux emulated the _r_debug structure, normally maintained by ld.so, but that cannot be done in SGX outer PAL, because it's loaded by ld.so already. - Maintain the debug maps outside of SGX enclave. This allows initializing them before enclave start, and potentially makes them easier to use. - Initialize PAL debug map before enclave start. Previously, this was done from inside the enclave, so you couldn't set a breakpoint too early (e.g. in pal_linux_main). - Store only load address, without list of sections. This is to avoid parsing the list of sections just to report them to the debugger. Unfortunately, the GDB version that we support still needs these sections, but we can retrieve them in GDB plugin. - Move Python GDB code related to debug maps to a common file.
