[PATCH v3 38/49] builtin/apply: move 'squelch_whitespace_errors' into 'struct apply_state'

[Christian Couder <christian.couder@xxxxxxxxx>]

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