2768beec4c ADDED: path_segments/2 for portable reasoning about path components. 
The platform-specific directory separator is taken into account.
The clean representation of segments as a list simplifies reasoning.

17dd9239b6 ADDED: file_creation_time/2 and file_access_time/2. 
The code can be simplified once if- and while-let-chains are available:

88a2b82f7e ENHANCED: library(crypto): Retain the compact representation of strings. 
This avoids the costly (in terms of space requirements!) conversion of
compact lists of characters to lists of integers, making hashing, HKDF,
encryption, decryption, signing and signature verification an order of
magnitude more efficient (primarily in terms of space, also in time).

This makes library(crypto) suitable to process also very large files.

eb872f8fca ADDED: library(os), reasoning about environment variables. 
Together with library(files), this addresses #511.

8958ea036e ENHANCED: much faster format/3 for text streams 
This is now also used by format/2 to emit output on the terminal,
and significantly speeds up toplevel output of long strings.

409d3c168d ENHANCED: faster format/3 when writing to binary streams 
This is also more secure, since it does not change the atom table
and therefore leaves little trace of what was processed.
