httpuv 1.5.2 release checklist

[x] If not a new package, make sure any warnings/errors in CRAN check results page are fixed
[x] Build and check on Centos 6. (might need this)
[x] Create RC branch rc-v1.5.2
[x] Change the DESCRIPTION and NEWS on this branch to change the version number to the desired version for CRAN
[x] Perform Shiny final test pass on rc-v1.5.2
[x] Clean your package directory to remove any extraneous files, including ones that are git-ignored. (Warning, this will delete any unsaved buffers in RStudio! Also, be sure to close RStudio before taking this step!) git clean -xdi .
[x] Build your package. I (jcheng) personally do it from the Mac command line like this: PATH=$PATH:/Applications/RStudio.app/Contents/MacOS/pandoc R CMD build [pkgdir]
[x] Do a sanity check by installing/testing the built package.
[x] Perform revdep check using https://github.com/r-lib/revdepcheck, if this is not the initial CRAN release.
[x] Run R CMD check --as-cran pkg_version.tar.gz both locally and on win-builder. You can also use https://r-hub.github.io/rhub/.
[x] Review CRAN Policies document
[x] Submit to CRAN via their online form.
[x] When accepted, tag the RC branch with a v1.5.2 tag (or whatever version you finally ended up getting accepted), and push the tag to origin.
[x] Merge RC into master.
[x] On master, change the package version to 1.5.2.9000.
