Georgi Kodinov a9a2ceae1f Bug #51850: crash/memory overlap when using load data infile and set 
col equal to itself!

There's no need to copy the value of a field into itself.
While generally harmless (except for some performance penalties)
it may be dangerous when the copy code doesn't expect this.
Fixed by checking if the source field is the same as the destination
field before copying the data.
Note that we must preserve the order of assignment of the null 
flags (hence the null_value assignment addition).

# Bug#37114: sql_mode NO_BACKSLASH_ESCAPES does not work properly with
# LOAD DATA INFILE
#
# - For each plain "SELECT id,...", the 1st pair ("before" SELECT...OUTFILE,
# LOAD...INFILE) and the 2nd pair of lines ("after") in the result should
# look the same, otherwise we broke the dumpe/restore cycle!
#
# - the \r is always { '\\', 'r' } in memory, but on-disk format changes
#
# - the \t is { '\t' } or { '\\', 't' } in memory depending on whether \
# is magic (that is, NO_BACKSLASH_ESCAPES is not set) at INSERT-time.
# on-disk format varies.
#
# - while INFILE/OUTFILE behaviour changes according to NO_BACKSLASH_ESCAPES,
# we can override these defaults using ESCAPED BY '...'
# 1: NO_BACKSLASH_ESCAPES default, \ on-disk: \,t,x,\r
# 2: NO_BACKSLASH_ESCAPES override, \\ on-disk: \,\,t,x,\,\,r
# 3: !NO_BACKSLASH_ESCAPES default, \\ on-disk: tab,\,\,r
