Lossless optimization of png image files, using `pngslim` and other tools.
Program graphics (compiled or included with software):
- Slimmed 28.7 KiB (~28.5 KiB kpacked), average ~19% saving for 13 files.
Documentation only artwork (distributed outside of a program):
- Slimmed 100 KiB (~91 KiB kpacked), average ~38% saving for 27 files.

- Duplicate functionality files removed;
- Refactoring of file handling functions;
- Removed broken impliments.
Gears (C + TinyGL):
- Removed because it duplicates an existing example on Fasm and uses unsupported wrappers on the KOS API.
KosJS:
- Removed. The MuJS port is too old and not used anywhere. Support is not profitable.
Backy:
- Removed useless GCC version. Support is not profitable.
DGen-SDL and SQLite3
- Fix after removing broken "dirent.h".
Fridge:
- Moving the KOS API wrapper to avoid compilation errors.
Udis86, uARM and 8086tiny:
- Fix after removing redundant "kos_LoadConsole.h".

Commit e63ed12ead17e47d77e848da0e7b9f4dd3ad5127
Bugfix: Make it able to write more than 64k - 1 COFF relocations
If the relocation count is greater than 0xffff then it can't fit
in the NumberOfRelocations field of a section header. In order to
specify greater relocation count IMAGE_SCN_LNK_NRELOC_OVFL flag
should be added to Characteristics and the actual relocation count
should be written into VirtualAddress field of the first COFF
relocation.

Bugfix: Make it able to read more than 64k - 1 COFF relocations
New EPEP API allows to read more than 64k - 1 relocations. Use it
when reading relocation count for filling SectionInfo and when
reading relocations for wriring the output file.

Commit 3bed4e348a486c346d0a452c58c1d85e1805c09d
Feature: Higher-level COFF relocations API
Number of COFF relocations of a section is stored in the 16-bit
NumberOfRelocations field of a section header. If a COFF object has
more than 2^16 - 1 relocations, then the value does not fit in the
field.
To solve this problem, IMAGE_SCN_LNK_NRELOC_OVFL flag of a section
header has been introduced. If this flag is set for the section,
then the actual number of relocations is stored in the
VirtualAddress field of the first relocation.
If the flag is set, then NumberOfRelocations field of the section
header should be equal to 0xffff, othervice the linker should give
an error.
So this patch introduces few functions adressing this mechanism.
epep_section_contains_extended_relocations:
Checks whether the section has more than 2^16 - 1 relocations.
Retrns error if the IMAGE_SCN_LNK_NRELOC_OVFL flag is set, but
the NumberOfRelocations field is not equal to 0xffff.
epep_get_section_extended_number_of_relocations:
Reads the number of COFF relocations from the VirtualAddress
field of the first COFF relocation.
epep_get_section_number_of_relocations_x:
Gives the number of meaningful relocations of the section.
If the section has less than 2^16 relocations, then returns the
value of the NumberOfRelocations field of the section header,
othervice reads the number of relocations from the first COFF
relocation, but: since the first relocation in this case is not
meaningful, gives the actual number of relocations minus one.
This is used in the function documented below.
Returns 1 in the last argument if the section contains extended
number of relocations, 0 othervice.
epep_get_section_relocation_by_index_x:
If the section has less than 2^16 relocations, then just reads
a relocation by the given index. In case if the section has
extended number of relocations, the first relocation is not
meaningful, so it is skipped, and the relocation at index + 1
is read instead.
