hedley is a single header to handle compiler-specific features:
https://nemequ.github.io/hedley/
Prefer headly macros over glib for now.

- the parser didn't require a comma before, and accepted multiple ones
- comma at end of list still optional

conditional expressions include values to compare with; any
complicated value expression must be put into parantheses.
-> stop parsing after a simple value, don't search for operators,
"and"/"or" operators are handled by the conditional
* no more hash values - only lists and list of key-value pairs
* "master" config:
the config loaded on startup can use all features,
configs loaded later (vhost on demand from sql...) can't use
include* and cannot modify global vars.
* scoped variables
- add a global var store in the server struct
- global vars can be set with "global foo = bar"
- if a variable already exists in a scope it will be modified on a
write, otherwise a new local variable is created
- global vars won't be modified if not in "master" mode
- vars can be made explicitly local with "local foo = bar"; create a
local copy with "local foo = foo"
- globals vars are available in live config loads for reading
- each file and action block {...} creates a new scope; if/else branches do
NOT create a new scope
* to append a value to a list use "l + [v]" (not "l + v" anymore);
lists are concatenated with "+"
* [...] always marks a list
* (...) is a list if it contains a "," or "=>", otherwise it justs
groups an expression
* a list can either contain key-value pairs or other values. mixing is
not allowed
* should be more robust now: taking list of wanted value, handling NULL
pointers instead of value type NONE, fixed some bugs (wrong checks,
mem leaks, ...)
* add many methods to make handling of values easier; most methods
can handle NULL value pointers safely (li_value_type(v) instead of
v->type and so on)
* Change ":" to "=>" in hash tables
* Change assignments to not need "=" anymore
* User defined actions must now be prefixed with the "action" keyword
* Anonymous user defined actions don't need the "$" prefix anymore
* Fix parsing of conditionals with more than 2 conditions
