Change the default of --enable-assume-ram from 32 to 128 MiB. 

This is to allow files created with "xz -9" to be decompressed
if the amount of RAM cannot be determined.

On some systems, there is no code to detect the amount of
RAM though. Using --enable-assume-ram one can set how much
memory to assume on these systems. SIZE is given as MiB.
The default is 32 MiB, which is probably too low for most
systems, but it is enough to allow decompressing .xz files
created with the default settings.
The default is 128 MiB, which allows decompressing files
created with "xz -9".
Feel free to send patches to add support for detecting
the amount of RAM on the operating system you use. See
