[PATCH 09/10] fs: allocate FILE table dynamically

[Sascha Hauer]

Some systems are runnignfrom a very limited SRAM, but have a huge
malloc space in SDRAM. The bss normally is in SRAM, so we should
avoid having big structures there. The FILE table is 5120 bytes
big, so allocate it dynamically instead.
