/*
Read record from datafile.
SYNOPSIS
_mi_read_dynamic_record()
info MI_INFO pointer to table.
filepos From where to read the record.
buf Destination for record.
NOTE
If a write buffer is active, it needs to be flushed if its contents
intersects with the record to read. We always check if the position
of the first byte of the write buffer is lower than the position
past the last byte to read. In theory this is also true if the write
buffer is completely below the read segment. That is, if there is no
intersection. But this case is unusual. We flush anyway. Only if the
first byte in the write buffer is above the last byte to read, we do
not flush.
A dynamic record may need several reads. So this check must be done
before every read. Reading a dynamic record starts with reading the
block header. If the record does not fit into the free space of the
header, the block may be longer than the header. In this case a
second read is necessary. These one or two reads repeat for every
part of the record.
