unescape: fix casting char to uint32_t on arm inconsistent with x86

This patch fix casting issue where casting char to uint32_t on arm is
inconsistent with x86, because char is unsigned char by default on arm,
but signed char on x86, so need to do a explicit conversion before casting
char to uint32_t.

in_tail: fix handling of long lines

This patch restores the behavior of expanding the buffer upto buffer_max_size before
skipping a line that is too long. It also correctly marks the offset after skipping
the long line
