Add imageConfig function which calls image.DecodeConfig and returns the height, width and color mode of the image. (#2677)
This allows for more advanced image shortcodes and templates such as those required by AMP.
layouts/shortcodes/amp-img.html
```
{{ $src := .Get "src" }}
{{ $config := imageConfig (printf "/static/%s" $src) }}
<amp-img src="{{$src}}"
height="{{$config.Height}}"
width="{{$config.Width}}"
layout="responsive">
</amp-img>
```
tpl/template_funcs.go:1019:3: the surrounding loop is unconditionally terminated
source/lazy_file_reader.go:66:5: err != nil is always true for all possible
values ([nil:error] != [nil:error])
This commit adds a `GitInfo` object to `Page` if `EnableGitInfo` is set.
It then also sets `Lastmod` for the given `Page` to the author date provided by Git.
The Git integrations should be fairly performant, but it adds "some time" to the build, somewhat depending on the Git history size.
If you want, you can run without during development and turn it on when deploying to the live server: `hugo --enableGitInfo`.
Fixes#2102
changes:
- in hugolib/page.go, `func permalink` and `func TargetPath`
Fixed the attempt to *replace* the extension of something
that was *already* a basename.
- in source/file.go, `func NewFile`
added check for allowed languages before translating filename
Fixes#2555
- removed comma on line 16 to avoid confusion between clauses
- added period to line 24 for consistency
- clarified "read on" on line 30 to follow style above it while
also verbally writing what the author seems to intend
- removed "You probably know what to do." on line 30 due to wordiness
that could lead to confusion and a drag in reading speed
- changed preposition into intended infinitive for syntactical clarity
- removed "easily" as it doesn't describe anything technical and is
confusing (which is why the author may have used a preposition)
All config variables starts with low-case and uses camelCase.
If there is abbreviation at the beginning of the name, the whole
abbreviation will be written in low-case.
If there is abbreviation at the end of the name, the
whole abbreviation will be written in upper-case.
For example, rssURI.
The gain, given the "real sites benchmark" below, is obvious:
```
benchmark old ns/op new ns/op delta
BenchmarkHugo-4 14497594101 13084156335 -9.75%
benchmark old allocs new allocs delta
BenchmarkHugo-4 57404335 48282002 -15.89%
benchmark old bytes new bytes delta
BenchmarkHugo-4 9933505624 9721984424 -2.13%
```
Fixes#2495
Add logging of the errors/warnings which rst2html outputs to its stderr
stream when rendering rst documents. Note that rst2html outputs warnings
and errors to stderr but it also adds them to the generated html. ->
hugo logs everything in stderr as error.
Add / complete adding page context (path to file being rendered) to
anything logged by getRstContent and getAsciidocContent.
See #2570
Also refactor the rendering pages test to accept more than one page source per test run, which wasn't really needed for this issue, but may be in the future.

Maps in Viper, Hugo's config backing store, is now properly lower-cased not just on top level, the current situation.
While this is mostly a good thing, as you don't need to know the original casing to look up a value, it will be breaking for people doing direct lookups in the ´Site.Params` map.
We will try to find a solution to this "breakage", but the recommended method to get params values is via the `.Param` methods.
This method is now implemented on `Node`, `Page` and `Site` and is case-insensitive:
* Use `.Param "someKey" ` if you want page param with fall back to site param if not found on page.
* Use `.Site.Param "someKey"` to get a site param
See #2590
