[PATCH v4 2/2] builtin/apply: move 'newfd' global into 'struct apply_state'

[Christian Couder <christian.couder@gmail.com>]

From: Christian Couder <christian.couder@gmail.com>

To libify the apply functionality the 'newfd' variable should
not be static and global to the file. Let's move it into
'struct apply_state'.

This is to replace:

[PATCH v3 49/49] builtin/apply: move 'newfd' global into 'struct apply_state'

from the "libify apply and use lib in am, part 1" patch series.

There is no change compared to the previous version except that this
patch should apply cleanly on top of PATCH v4 1/2.
