Carsten Haitzler a5c8e883d8 eina mmap safety - only map zeropages if it's an eina file that sigbuses 
restrict mapping /dev/zero to only eina files having a sigbus
reported. the mmap was before all our file access used eina_file i
think thus the raw mmap of it. now walk all eina files and find the
candidate and only then if it exists flag is as having a faulty i/o
backing and map the zerto pages then return, otherwise call abort.
more restricted mapping and perhaps a fix for not trapping non-efl
issues.

Carsten Haitzler 615456aae8 eina - mmap safety handler - fix to only handle sigbus's from io 
@fix

this fixes the eina mmap safety handler to only  handle what comes
from actual i/o errors (not actual corrupt/hw memory faults or invalid
objects), and if it's not a sigbus eina mmap should handle then pass
it onto the previous handler before eina mmap took over.

Cedric BAIL 884c31df41 eina: fix siginfo detection. 
Signal are not a portable way to detect memory mapped file corruption.
So let's disable it for system without signal and later find a way to
detect it on other system.
