Version 5.1.0

Changes since v5.0.0:

Repository structure and other general changes

• #58 : Moved printf.h and printf.c into the src/ directory

Build configuration

• #59: Unified names of CMake variable and C preprocessor defines for the integer-to-string buffer size. It's now PRINTF_INTEGER_BUFFER_SIZE everywhere.
• #54: Changed the mechanism for aliasing the standard printf() family of functions. (And it's not broken now...)

Library API changes

• #55: Using putchar_() instead of _putchar().

Code formatting, naming, comments etc.

• #54: Avoiding the ifdef-if preprocessor directive idiom, in favor of ifndef-define-endif-if.
• Change include guard name - avoiding heading underscore.

Other issues

• Dropped Travis CI metadata file.
• README.md documentation update
• More pedantic use of NULL in the test suite.
• Fixed: Was not passing TEST_WITH_NON_STANDARD_FORMAT_STRINGS properly to the test suite.
• Added a test for aliasing the standard library's printf(): aliasing.cpp
• Change include guard name - avoiding heading underscore.
• #52: Test suite no longer checks for "10e+2", "10e+5" etc. but rather "1e+3", "1e+6" etc. (like it should.)
• Disabling a format warning about invalid formats, which we are testing as such intentionally.

Caveats

• Still no special handling for denormals.
