Dmitry Vyukov 41799debdc prog: introduce more readable format for data args 
Fixes #460

File names, crypto algorithm names, etc in programs are completely unreadable:

bind$alg(r0, &(0x7f0000408000)={0x26, "6861736800000000000000000000",
0x0, 0x0, "6d6435000000000000000000000000000000000000000000000000
000000000000000000000000000000000000000000000000000000000000000
00000000000"}, 0x58)

Introduce another format for printable strings.
New args are denoted by '' ("" for old args).
New format is enabled for printable chars, \x00
and \t, \r, \n.

Example:
`serialize(&(0x7f0000408000)={"6861736800000000000000000000", "4849000000"})`,
vs:
`serialize(&(0x7f0000408000)={'hash\x00', 'HI\x00'})`,
