ba467ce430 Make the structure for handling the input stack local to the parse
module. The only module accessing it (the current line number) was the
condition module, so pass the current line number as a function argument.
Centralize the pushing of new input sources into one function
ParsePushInput() and rename the function handling the popping from ParseEOF()
to ParsePopInput(). Make the entire thing a little bit clearer, by holding
the current input source in the top element of the stack instead of
using extra variables for this. Use a type-safe intrusive list for the
input stack.

f43eb6f83b Fix a bug introduced in a previous commit: ParseModifier() consumes
characters so it is not safe to move around code from
before it to after it. This should fix problems with building the
documentation.

7ea59d002e Fix a bug in matching suffixes. Under certain circumstances the code
would access memory before the beginning of the string to match (the
suffix match starts at the end of both the string and the suffix and
proceedes to the begin until either the start of the suffix is hit
or the character does not match). This could lead to a memcpy copying
into random memory. Fix this by checking the length of the string to
match too and replacing the Lst_Find calls with LST_FOREACH loops
(last part by me).

d057118357 Var_Parse: Separate different error states by introducing an else block
after a return. Move assignments to {freePtr, dynamic, start} closer to the
return statements to clarify which variables are actually used for
communication between the losely coupled blocks of the code. Clear up
an if-expression to make common structures of the conditions clearer.
Use strchr instead of switch statements to check for a character beeing
a member of a set.

36120d91e5 Invent the LST_FOREACH macro for looping through a list. In contrast
to the Lst_ForEach function this macro reduces the number of function

and increases code locality thereby increasing readability and
(maybe) performance.

436834581b Fix a bug in handling archive members: when a member was not found
when looking into an already hashed archive, the code tried to use
the name shortened to the maximum length allowed for the archive.
Unfortunately it passed a buffer of junk to the hashing routine when
the name actually wasn't too long. Theoretically this could lead to
a false positive.
