Konstantin Belousov b32ecf44bc Flip the semantic of M_NOWAIT to only require the allocation to not ... sleep, and perform the page allocations with VM_ALLOC_SYSTEM class. Previously, the allocation was also allowed to completely drain the reserve of the free pages, being translated to VM_ALLOC_INTERRUPT request class for vm_page_alloc() and similar functions. Allow the caller of malloc* to request the 'deep drain' semantic by providing M_USE_RESERVE flag, now translated to VM_ALLOC_INTERRUPT class. Previously, it resulted in less aggressive VM_ALLOC_SYSTEM allocation class. Centralize the translation of the M_* malloc(9) flags in the single inline function malloc2vm_flags().
