[Buildroot] Replace libev with libuv

Nimai, All,

Please, do *not* top-post. Reply in-lined, like I do below...

There is a configuration glitch that makes cgit not show all commits.
Compare:
    http://git.buildroot.org/buildroot
    http://git.buildroot.org/buildroot/

The former (without the ending '/') is always up-to-date, while the
latter (with the ending '/') often lags behind, by up to a few days.

Nope, that's probably your mailer trying to be too smart, and replacing
all '@' sy,mbols with '<at>' in an attempt to thwarte spammers from
harvesting email addresses.

Do not hesitate to post new packages! Reviews are here to catch problems
in the submissions, and to direct the submitter to the adequate
ressources to fix potential issues.

A good way to add a new package in Buildroot is to:
  - look at the manual: http://buildroot.net/downloads/manual/manual.html
  - look at existing packages

Well, it all depends. Buildroot can handle a few common, generic build
systems and types of packages, as you'll see in the manual ;-) :
  - autotools,
  - cmake
  - python
  - lua
  - perl

But it also handles packages with a specific build system, such as plain
Makefiles.

So, it is not required to convert packages to include them in Buildroot.

Yann E. MORIN.
