indent(1): Use a dash in the license headers. Use of the canonical dash avoids indent(1) from reformatting the license headers.

various: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

int count_spaces(int, char *);
indent(1): Simplify pr_comment(). Modify count_spaces() to take a third parameter "end" that will make the function return when the end is reached. This lets the caller pass a pointer to non nul-terminated sequence of characters. Rename count_spaces() to count_spaces_until() and reinstate count_spaces(), this time based on count_spaces_until(). Use count_spaces_until() to recalculate current column when going through a comment just before the fragment which decides if current line of the comment should be wrapped. This move simplifies this code by eliminating the need for keeping the column counter up to date every time e_com is advanced and also reduces spread of code that has to know how many columns a tab will produce. Deduplicate code that decided if a comment needs a blank line at the top.

indent(1): rewrite the integer/floating constant scanning part of lexi.c Remove procedural code that did the scanning, which was faulty and didn't support complex constants such as 0x1p-61. Replace it with a finite state machine expressed as a transition table. The table was rewritten by hand from lx's output, given parts of grammar expressed as regular expressions. lx is Katherine Flavel's lexer generator, currently available at https://github.com/katef/libfsm and the parts of grammar were taken from http://quut.com/c/ANSI-C-grammar-l-2011.html and extended to support binary integer constants which are a popular GCC extension.

void init_constant_tt(void);
indent(1): improve predictability of lexi() lexi() reads the input stream and categorizes the next token. indent will sometimes buffer up a sequence of tokens in order rearrange them. That is needed for properly cuddling else or placing braces correctly according to the chosen style (KNF vs Allman) when comments are around. The loop that buffers tokens up uses lexi() to decide if it's time to stop buffering. Then the temporary buffer is used to feed lexi() the same tokens again, this time for normal processing. The problem is that lexi() apart from recognizing the token, can change a lot of information about the current state, for example ps.last_nl, ps.keyword, buf_ptr. It also abandons leading whitespace, which is needed mainly for comment-related considerations. So the call to lexi() while tokens are buffered up and categorized can change the state before they're read again for normal processing which may easily result in changing interpretation of the current state and lead to incorrect output. To work around the problems: 1) copy the whitespace into the save_com buffer so that it will be read again when processed 2) trick lexi() into modifying a temporary copy of the parser state instead of the original.

int lexi(struct parser_state *);
1) Const enough things to avoid warnings. 2) Cast ifdef_level to a size_t before comparing it to a ratio of size_ts. Ifdef_level should always be positive. 3) Complete prototype for chfont. 4) Cast some ptrdiff_ts to ints before using as a field width. 5) Avoid shadowing a local variable p with another local variable p.

indent(1): add option -P for loading user-provided files as profiles Without this change, indent(1) would only look to load options from ~/.indent.pro if it's there and -npro wasn't used on the command line. This option lets the user set their own path to the file. Approved by: pfg (mentor) Differential Revision: https://reviews.freebsd.org/D9010
