Made corrections to some old errors.
*Corrected the method signature for MODLOAD's ReBootStart() function.
*Moved the smod_mod_info_t structure from iopmgr to loadcore.h as ModuleInfo_t, as LOADCORE's export #3 actually uses it.
*Renamed GetLibraryEntryTable() of LOADCORE to GetLoadcoreInternalData(), as it actually returns a pointer to loadcore's internal data.
*GetLibraryEntryTable(), iop_library_table_t and smod_mod_info_t have been retained for backward-compatibility with older projects, but have been marked as deprecated.
*GetLoadCoreInternalData() returns lc_internals_t instead, which is the complete version of iop_library_table_t.
*Fixed up all other modules in the PS2SDK to use GetLoadCoreInternalData() and ModuleInfo_t instead.
*Changed all modules that assume that the module table starts at 0x800 to use GetLoadCoreInternalData()->image_info instead. This address of 0x800 can actually be changed.
*Added (exported) inet_aton() and inet_ntoa() of LWIP v1.1.1.
*Added (exported) ipaddr_aton(), ipaddr_ntoa() and inet_ntoa_r() of LWIP v1.4.1.
*Renamed the function prototype of inet_addr() of all LWIP v1.4.1 ports to ipaddr_addr() as there's actually no such function as inet_addr() in this network protocol stack.
