* fix: bug in previous refactor

* fix: do not leak absolute paths
* refactor/fix: batch extensions checking, fix DOS issue
This fixes a future problem when code is placed under a namespace because `get_class($bridge)` will then return e.g. `RssBridge\Bridge\TwitterBridge` instead of the the current value `TwitterBridge`.
Also a bit refactoring of `Configuration.php`.
Default bridges are currently statically defined in index.php, which
is not the right place if we want to keep responsibilities separated.
This commit introduces a new file whitelist.default.txt that holds
the default bridges and which is loaded automatically, if whitelist.txt
doesn't exist.
Due to this it is also no longer necessary to have write permission
for the root directory.

Fix PHP Notice: Undefined offset: 0. Error below triggers when there are no items:
PHP Notice: Undefined offset: 0 in C:\php\rss-bridge\index.php on line 249
Add transformation from legacy items to FeedItems, before transforming
items to the desired format. This allows using legacy bridges alongside
bridges that return FeedItems.
As discussed in #940, instead of throwing exceptions on invalid
parameters, add messages to the debug log instead
Add support for strings to setTimestamp(). If the provided timestamp
is a string, automatically try to parse it using strtotime().
This allows bridges to simply use `$item['timestamp'] = $timestamp;`
instead of `$item['timestamp'] = strtotime($timestamp);`
Support simple_html_dom_node as input paramter for setURI
Support simple_html_dom_node as input parameter for setContent
* core: Add bridge parameter auto detection
This adds a new 'detect' action which accepts a URL from which an
appropriate bridge is selected and relevant parameters are extracted.
The user is then automatically redirected to the selected bridge.
For example to get a feed from: https://twitter.com/search?q=%23rss-bridge
we could send a request to:
'/?action=detect&format=Atom&url=twitter.com/search%3Fq%3D%2523rss-bridge'
which would redirect to:
'/?action=display&q=%23rss-bridge&bridge=Twitter&format=Atom'.
This auto detection happens on a per-bridge basis, so a new function
'detectParameters' is added to BridgeInterface which bridges may implement.
It takes a URL for an argument and returns a list of parameters that were
extracted, or null if the URL isn't relevant for the bridge.
* [TwitterBridge] Add parameter auto detection
* [BridgeAbstract] Add generic parameter detection
This adds generic "paramater detection" for bridges that don't have any
parameters defined. If the queried URL matches the URI defined in the
bridge (ignoring https://, www. and trailing /) an emtpy list of parameters is
returned.
Requesting `_cache_timeout` on servers where this option is disabled currently results in the error message 'This server doesn\'t support "_cache_timeout"!'. This commit changes that behavior to redirect to the query without `_cache_timeout`.
- Move all whitelisting functionality inside Bridge.php
- Set default whitelist once in index.php using Bridge::setWhitelist()
- Include bridge sanitizing inside Bridge.php
Bridge::sanitizeBridgeName($name)
Bridge.php now maintains the whitelist internally.
Also adds documentation to Debug.php!
* Debug::isEnabled()
Checks if the DEBUG file exists on disk on the first call (stored in
memory for the duration of the instance). Returns true if debug mode
is enabled for the client.
This function also sets the internal flag for Debug::isSecure()!
* Debug::isSecure()
Returns true if debuging is enabled for specific IP addresses, false
otherwise. This is checked on the first call of Debug::isEnabled().
If you call this function before Debug::isEnabled(), the default value
is false.
- PATH_LIB_BRIDGES defines the path to bridges
- PATH_LIB_FORMATS defines the path to formats
- PATH_LIB_CACHES defines the path to caches
Include constants in RssBridge.php for consistency
Move CACHE_DIR from index.php to /lib/RssBridge.php and change name
to PATH_CACHE.
PATH_CACHE is one of the core paths of RSS-Bridge and should therefore
be defined in the core file RssBridge.php.
The parameter is used in error feeds. Since RSS-Bridge returns valid
feeds for error conditions, feed readers may attempt to access the
URI returned for the feed item in order to collect additional data,
thus including the parameter '_error_time' in the query.
This results in another error message, because it is an invalid input
parameter. Filtering the parameter allows RSS-Bridge to return the
original feed.

Exceptions are reported to users, but they do not necessarily appear
in the error log on the server. Using 'error_log' we can explicitly
write exceptions and error messages to the log file, using the
standard PHP message format.
