Add some basic checks for isc_buffer_copyregion() to ensure it behaves
as expected for both fixed-size buffers and buffers which can be
automatically reallocated. Adjust the list of headers included by
lib/isc/tests/buffer_test.c so that it matches what that test program
really uses.
(cherry picked from commit 15440d8027)
provisioning secondary servers in which a list of
zones to be served is stored in a DNS zone and can
be propagated to slaves via AXFR/IXFR. [RT #41581]
4375. [func] Add support for automatic reallocation of isc_buffer
to isc_buffer_put* functions. [RT #42394]
4005. [func] The buffer used for returning text from rndc
commands is now dynamically resizable, allowing
arbitrarily large amounts of text to be sent back
to the client. (Prior to this change, it was
possible for the output of "rndc tsig-list" to be
truncated.) [RT #37731]
