scripts/gdb: lx-dmesg: read records individually
For the gdb command lx-dmesg, the entire descriptor, info, and text
data regions are read into memory before printing any records. For
large kernel log buffers, this not only causes a huge delay before
seeing any records, but it may also lead to python errors of too
much memory allocation.
Rather than reading in all these regions in advance, read them as
needed and only read the regions for the particular record that is
being printed.
The gdb macro "dmesg" in Documentation/admin-guide/kdump/gdbmacros.txt
already prints out the kernel log buffer like this.
