* Change git packages to xz
* Update mirror checksums in packages where they are used
* Change a few source tarballs to xz if available upstream
* Remove unused lines in packages we're touching, requested by jow- and blogic
* We're relying more on xz-utils so add official mirror as primary source, master site as secondary.
* Add SHA256 checksums to multiple git tarball packages

Now that the uhttpd init script can generate certificates using openssl as
well, update the section name and related comment to be more generic.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
Support the usage of the OpenSSL command-line tool for generating
the SSL certificate for uhttpd. Traditionally 'px5g' based on
PolarSSL (or mbedTLS in LEDE), has been used for the creation.
uhttpd init script is enhanced by adding detection of an installed
openssl command-line binary (provided by 'openssl-util' package),
and if found, the tool is used for certificate generation.
Note: After this patch the script prefers to use the OpenSSL tool
if both it and px5g are installed.
This enables creating a truly OpenSSL-only version of LuCI
without dependency to PolarSSL/mbedTLS based px5g.

Configurations without shadow passwords have been broken since the removal
of telnet: as the default entry in /etc/passwd is not empty (but rather
unset), there will be no way to log onto such a system by default. As
disabling shadow passwords is not useful anyways, remove this configuration
option.
The config symbol is kept (for a while), as packages from feeds depend on
it.

Match sections allow to set a tag specified by the option networkid if the client
sends an option and optionally the option value specified by the match option.
The force option will convert the dhcp-option to force-dhcp-option if set to 1 in
the dnsmasq config if options are specified in the dhcp_option option.

Don't expose dnsmasq version & other data to clients via the *.bind
pseudo domain. This uses a new 'NO_ID' compile time option which has been
discussed and submitted upstream.
This is an alternate to replacing version with 'unknown' which affects
the version reported to syslog and 'dnsmasq --version'
Run time tested with & without NO_ID on Archer C7 v2

Regression introduced by 3481d0d dnsmasq: run as dedicated UID/GID
dnsmasq is unable to remove its own pidfile as /var/run/dnsmasq is owned
by root and now dnsmasq runs as dnsmasq:dnsmasq. Change directory
ownership to match.
dnsmasq initially starts as root, creates the pidfile, then drops to
requested non-root user. Until this fix dnsmasq had insufficient
privilege to remove its own pidfile.

PPP daemon can be put into persist mode meaning the
daemon will not exit after a connection gets terminated
but will instead try to reopen the connection.
The re-initiation after the link has been terminated
can be controlled via holdoff; this is helpfull in
scenarios where a BRAS is in denial of service mode
due to link setup requests after a BRAS has gone down
Following uci parameters have been added :
persist (boolean) : Puts the ppp daemon in persist mode
maxfail (integer) : Number of consecutive fail attempts which
puts the PPP daemon in exit mode
holdoff (interget) : Specifies how many seconds to wait
before re-initiating link setup after it has been terminated

* Only parse interfaces that are up during init_config (as the
script depends on this to determine the proper IP/subnet range)
* Add reload interface triggers for samba-designated interfaces
* Force full service restart upon config change to ensure Samba
binds to new interfaces (sending HUP signal doesn't work)
* Rename "interface" variable to "samba_iface" and move into
global scope
Needed to fix Samba connectivity for clients connecting from a
different LAN subnet (e.g. pseudobridge configurations) due to the
'bind interfaces only' setting.

- Security: Message printout was vulnerable to format string injection.
If specific usernames including "%" symbols can be created on a system
(validated by getpwnam()) then an attacker could run arbitrary code as root
when connecting to Dropbear server.
A dbclient user who can control username or host arguments could potentially
run arbitrary code as the dbclient user. This could be a problem if scripts
or webpages pass untrusted input to the dbclient program.
- Security: dropbearconvert import of OpenSSH keys could run arbitrary code as
the local dropbearconvert user when parsing malicious key files
- Security: dbclient could run arbitrary code as the local dbclient user if
particular -m or -c arguments are provided. This could be an issue where
dbclient is used in scripts.
- Security: dbclient or dropbear server could expose process memory to the
running user if compiled with DEBUG_TRACE and running with -v

Removed socket options = TCP_NODELAY IPTOS_LOWDELAY
TCP_NODELAY (disables Nagle algorithm) is default since samba2.
IPTOS_LOWDELAY sets DSCP 0x10 coding (CS2)
The alternate IPTOS_THROUGHPUT sets DSCP 0x08 coding (CS1)
CS1 is a scavenger class, whilst CS2 is more OAM/interactive
(SNMP,SSH,syslog)
Using CS2 is definitely an abuse of DSCP classification, CS1 less so
however even if the ISP takes note of DSCP codings having a default that
sets traffic to CS2 is wrong. Better to use the default Best Effort
class.

By default dnsmasq uses the time function; which returns the time since
Epoch; to retrieve the current time. On boards which have no realtime
clock this can lead to side effects when the time is synced via ntp
as the "time wrap" forces dhcp leases to be considered as expired.
By enabling the broken realtime clock build switch dnsmasq uses the
times utility which returns the number of clock tick.

Change dnsmasq's dnssec time check handling to use time validity
indicated by ntpd rather than maintaining a cross boot/upgrade
/etc/dnsmasq.time timestamp file. This saves flash device wear.
If ntpd client is configured in uci and you're using dnssec, then
dnsmasq will not check dnssec timestamp validity until ntpd hotplug
indicates sync via a stratum change. The ntpd hotplug leaves a status
flag file to indicate to dnsmasq.init that time is valid and that it
should now start in 'check dnssec timestamp valid' mode.
If ntpd client is not configured and you're using dnssec, then it is
presumed you're using an alternate time sync mechanism and that time is
correct, thus dnsmasq checks dnssec timestamps are valid from 1st start.

V2 - stratum & step ntp changes indicate time is valid
V3 - on initial flag file step signal dnsmasq with SIGHUP if running
V4 - only accept step ntp changes. Accepting both stratum & step could
result in unpleasant script race conditions
V5 - Actually only accepting stratum is the correct thing to do after
further testing
V6 - improve handling of non busybox ntpd
if sysntpd not executable
dnsmasq checks dnssec timestamps
else
sysntp script disabled - look for timestamp file - allows external mechanism to use hotplug flag file
sysntp script enabled & uci ntp enabled - look for timestamp file
sysntp script enabled & uci ntp disabled - dnsmasq checks dnssec
