[Buildroot] [PATCH v4 0/2] package/unscd: new package

[Doug Kehn]

$(APPLY_PATCHES) suggestion is not incorporated as the debian patches are
skipped due to 'Unsupported file type for ...' I'm not sure if updating
apply-patches.sh to handle patches with no extension is the right thing to do.
Patching the debain series and changing patch names to add .patch extension
seems like overkill when compared to just handling everything in the .mk.

systemd recipe/support is removed. systemd support is best left to someone
versed in systemd who desires to use unscd with systemd.

The BR2_GLIBC_NSCD suggestion is incorporated. However, I'm not sure what the
proper next steps are to properly install glibc nscd for both internal/external
toolchains. Is it sufficient, for now, to just define BR2_GLIBC_NSCD?

[Buildroot] [PATCH v4 1/2] package/unscd: new package

[Doug Kehn]

A daemon which handles passwd, group and host lookups for running
programs and caches the results for the next query. You only need this
package if you are using slow Name Services like LDAP, NIS or NIS+.

This particular NSCD is a complete rewrite of the GNU glibc nscd which
is a single threaded server process which offloads all NSS lookups to
worker children; cache hits are handled by the parent, and only cache
misses start worker children, making the parent immune to resource
leaks, hangs, and crashes in NSS libraries.

It should mostly be a drop-in replacement for existing installs using
nscd.

[Buildroot] [PATCH v4 2/2] toolchain/toolchain-common.in: install nscd

[Doug Kehn]

Add BR2_GLIBC_NSCD for installing nscd. BR2_GLIBC_NSCD can be used by
other packages (e.g. unscd) to prevent the selection of multiple nscd
packages.

 Actually it would be good to modify apply-patches to apply everything when it
comes out of a series file.

 Patch follows.
