+ build-fix for PDCurses with ncurses-examples.
+ improved CF_CC_ENV_FLAGS.
+ modify configure scripts to reduce relinking/ranlib during library
install (Debian #903790):
+ use "install -p" when available, to avoid need for ranlib of
static libraries.
+ modify scripts which use "--disable-relink" to add a 1-second
sleep to work around tools which use whole-second timestamps, e.g.,
in utime() rather than the actual file system resolution.
+ add "--disable-touching" option for using "install -p" option during
the install, e.g., so that header-files have a predictable timestamp.
+ modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
avoid expansion of "CUR" in trace.
+ improve a few lintian warnings in test-packages.
+ modify lib_setup to avoid calling pthread_self() without first
verifying that the address is valid, i.e., for weak symbols
(report/patch by Werner Fink).
+ modify generated terminfo.5 to not use "expand" and related width
on the last column of tables, making layout on wide terminals look
better (adapted from patch by Kir Kolyshkin).
+ add a category to report_offsets, e.g., "w" for wide-character, "t"
for threads to make the report more readable. Reorganized the
structures reported to make the categories more apparent.
+ simplify some ifdef's for extended-colors.
+ add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
how similar the different tinfo configurations are.
+ modify command-line parameters for "convert" used in picsmap to work
with ImageMagick 6.8 and newer.
+ fix build-problem with tack and ABI-5 (Debian #868328).
+ repair termcap-format from tic/infocmp broken in 20170701 fixes
(Debian #868266).
+ reformat terminfo.src with 20170513 updates.
+ improve test-packages to address lintian warnings.
