@brief Concatenate the list of segments into a Unix-style path.
This function assumes a forward slash path separator (i.e. `/`).
@param n
The number of segments to join together.
@param segments
The path components to join together.
@return
The concatenation of the path components via `/`. The caller takes ownership
of this value.

@brief Perform case insensitive string comparison.
This function operates like `strcmp` except comparison ignores case.
@param s1
C string to be compared.
@param s2
C string to be compared.
@return
An integral value indicating the relationship between the strings:
- `< 0`: the first character (converted uppercase) that does not match has a
lower value in @p s1 than in @p s2.
- `= 0`: the contents of both strings are equal.
- `> 0`: the first character (converted uppercase) that does not match has a
greater value in @p s1 than in @p s2.
