apply some -Wno- to ignore several new warnings with GCC 10.


ntp: ignore truncation beyond api sizes, and ignore wrongly
guessed underflow

tmux: ignore maybe uninitialised warning for impossible case

libbfd: signed/unsigned variables assigned in the same statement

dri/gallium: -Wno-builtin-declaration-mismatch for u_atomic.c as
it implements backend functions with different in-C-machine but
same-in-real-machine types

libXfont/libXfont2: signed/unsigned variables assigned in the same
statement

i915drm: ignore impossible maybe uninitialised warnings

sysinst: ignore an invalid string truncation issue

Fix build; clean manpages only if they are generated automatically.

branches: 1.6.6; 1.6.8; 1.6.10; 1.6.24; 1.6.34;
adjust for new ntp and add the generated man pages

branches: 1.5.2; 1.5.6; 1.5.8; 1.5.16;
merge import ntp-4-2-6p5

branches: 1.4.4;
clean up man files copied during build

also.. while we are putting the pages into different sections,
lets change the manpage contents to reflect that

branches: 1.3.2;
Add -lterminfo after -ledit, so that this links when doing static
linking as well (found when building for the sun2 target).

add installation of manual pages, html files and up to now missing commands (sntp, ntptrace)

initial version of reachover make- and support-files
