Ignore punctuation marks in file name compare. Fix xstrcmp(). 
1. File name comparison method:
 - initially ignore white space and punctuation characters
 - run test for numeric values
 - if the remaining substrings match in case-insensitive compare, compare case
 - if they still match, see which one has more prefix symbols
 - if they still match, run a case-sensitive compare on complete strings

2. Fixed xstrcmp() to return diff instead of 0 and -1.

Use exact number of bytes for each filename. 
Results in even less memory usage. The names are appended one after another.
The offsets are reset when the location of the memory changes die to realloc().

Other changes:

1. Use a debug mode print to measure time.
2. Remove redundant prefix when printing pointers in debug mode.

An even faster nnn - no more copying file names! 
nnn has been using `struct entry` to hold both file name as well as file info.

The design forces file names to be copied in the following cases:

 - swaps during file sort (nnn uses quicksort) applied after all the matching
   files are read (in no particular order; good old readdir()) into memory.
 - swaps during manual filtering. nnn moves non-matching entries below so they
   are not encountered twice resulting in fast filtering.

There were scopes for _massive_ improvements in this area. So I did what had to
be done - decouple the file names from `struct entry` and use a separate struct
to hold the names with the indices set when the files are added by opendir().

There was a hidden problem to this approach - nnn uses realloc() to allocate
memory for file information and realloc() may move the original pointer in mem
when it can't fit the new memory to the earlier pointer. To handle that the new
algorithm tracks the change in memory location and re-adjusts the existing dir
entry names when that happens; this too, without any copying!

Though the results seem pretty clean from a theoretical point of view and early
tests, we may uncover some bugs. However, the speed is just mind-blowing!

And the binary size remains the same too!!!

Adjusting number of cols is redundant with shortening. 2017-09-01 10:45:10 +05:30
Arun Prakash Jana 1e5a0b8c5b
Fix #36: uneven splitting of codepoints 
Check if the number of columns needed to print name exceeds the number of cols.
If it does, split the name str at the max number of columns available for name.
Conversion to wide char ensures the split is done at a valid codepoint.

The current patch adds some optimization as well:

- No more copying to an intermediate (global) string.
- If the name is shortened, escape chars are replaced only till the terminator.

Fix cursor position issue with astral symbols 
In case of astral symbols like Devanagari matras multiple wide-char codepoints
occupy a single position/column. Positioning the cursor wrt. the actual number
of wide-characters in a wide-char string gets "visually incorrect".  The trick
is to calculate the correct number of columns needed to represent a fixed-size
wide-character string.
