588a542b2a sys: add string flags
Allow to define string flags in txt descriptions. E.g.:

  filesystem = "ext2", "ext3", "ext4"

and then use it in string type:

  ptr[in, string[filesystem]]

f085c198ba sys: replace FileoffType with IntType{Kind: IntFileoff}
FileoffType is effectively an int, no need for a separate type.
Also remove fd option from fileoff as it is unused and use story is unclear.

d3a93e8370 sys: attach Dir to all types
Dir is a static info, so we don't need to compute, propagate and
attach it in prog whenever we generate/change programs.
Attach Dir to all types.

959ec07095 sys: always use pointers to types
Currently we store most types by value in sys.Type.
This is somewhat counter-intuitive for C++ programmers,
because one can't easily update the type object.
Store pointers to type objects for all types.
It also makes it easier to update types, e.g. adding paddings.

852e3d2eae sys: support recursive structs
A struct can have a pointer to itself directly or indirectly.
Currently it leads to inifinite recursion when generating descriptions.
Fix this.

7690667267 sys: specify resources in text descriptions
Currently to add a new resource one needs to modify multiple source files,
which complicates descirption of new system calls.
Move resource descriptions from source code to text desciptions.

7db2edcb33 sys/sysgen/prog: support ranged int
This commit supports inclusive ranged int, like foo int32[-10~10], which will
generate random integer between -10 and 10. In future we will support more than
one range, like int32[0, -5~10, 50, 100~200]

4d3db6d4c8 host: detect unsupported syscalls
Also detect transitively unsupported syscalls,
that is, syscalls for which all syscalls that can create
input arguments are disabled.
