get_graphic_double() assigns lower_disp_limit twice and never writes
upper_disp_limit, so a DBR_GR_DOUBLE read of any DLYn field reports
the inverted range lower=10, upper=0. The second assignment was
evidently meant for the upper limit; the 0 in the upper slot is the
zeroed buffer dbAccess.c hands to the RSET, not a chosen value.
Both assignments date from commit 27e80be2e5 which introduced the
DLYn limits, so every release since 3.14.11 reports the inverted
range over both CA (DBR_GR/CTRL) and PVA (display.limitLow/High).
Extend seqTest with a DBR_GR_DOUBLE read of DLY0; the new cases
fail with lower=10, upper=0 before this fix.
In some cases the license-identification header was missing,
so I added that as well. Replaced the remaining headers that
specifically identified "Versions 3.13.7 and higher".
Makefiles and the build system were deliberately excluded.
