Previously, all datafiles/journals that were initially mapped were mapped with PROT_READ only, and later the memory protection was changed to PROT_READ | PROT_WRITE using mprotect().
However, on filesystems that are mounted with NOEXEC, changing the protection from PROT_READ to PROT_READ | PROT_WRITE later may fail. This has been reported in issue #2220.
This change now maps all datafiles/journals with PROT_READ | PROT_WRITE in the beginning, and will later change the mapping to PROT_READ if no writes are required
