Bug#45288: pb2 returns a lot of compilation warnings on linux

Fix assorted compiler warnings.

sql/mysqld.cc:
  Do not declare max_page_size twice. If large pages support
  is enabled, the code expects the size in max_desired_page_size.
storage/innobase/include/ibuf0ibuf.h:
  Remove trailing comma. Only present in C99.

storage/innobase/include/row0row.h:

strings/my_vsnprintf.c:
