Bug detected by go-fuzz (more fuzzing is required; need larger corpus)

We do this by returning an error and stopping link generation (which scans the markdown path for files)

Even if defined for multiple hosts. Startup or shutdown callbacks registered by any directive (startup, shutdown, markdown, git, log, etc.) will only run as many times as it appears in the Caddyfile, not repeated for each host that shares that server block. Fixing this involved refactoring three packages (yeesh) and we need to restore some tests that are no longer valid (that used to verify splitting a multiServerBlock into multiple serverBlocks).

Powers of 2, or base 1024, rather than powers of 10 or base 1000. The powers of 2 are technically more accurate.

Also, summary truncated at nearest space instead of middle of word, and code spans become part of summary.

markdown: Added test on static files generation

markdown: Add .Links action and flattened metadata structure

.Links available only for generated sites and variables no longer in a [variables] category in metadata (flat structure).

Fix more race conditions.

Fix race condition on parsers.
Added page links generator.

Test setup func for fastcgi.go

markdown: Change metadata variables type to map[string]string

Instead of map[string]interface{}

from map[string]interface{} to map[string]string

Open a redir block to bulk-specify a bunch of redirects that share a status code

markdown, browse: Integrated Context struct for templating

Put the title into the .Doc variables as well.
Changed the test template file to use new names.

This is a breaking change for those who expect catch-all redirects to preserve path; use {uri} variable explicitly now
