Description

As noted in ~~MDEV-33585~~, there is a limit on how much data a single system call can write. On FreeBSD, Linux, and Microsoft Windows, this limit would be much smaller than the size of a BLOB that could be buffered in a 64-bit address space of the server process.

Specifically, row_merge_write_blob_to_tmp_file() does not limit the size of a single os_file_write() request to at most 0x7fffff000 bytes, which is the limit on Linux.
