lib: Fix buffer code to satisfy static analyzers

Updated copyright notices to include the year 2018.

global: Fix spelling mistakes in comments Original work by @andreasschulze and @jsoref

lib: buffer_free(NULL) should be a no-op

Updated copyright notices to include the year 2017.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

global: Code cleanup - avoid passing NULL to functions with non-null parameter

lib: Add buffer truncate

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

Removed buffer_reset(). It was just a wrapper to buffer_set_used_size() and its comment was a bit confusing (or obsolete), since it wasn't actually immediately zeroing out the buffer.

lib: buffer_create_dynamic() now adds +1 to init_size

lib: Use p_malloc() explicitly in first buffer_alloc() Although there is now code in p_realloc() that it should be just as efficient, this makes profiling somewhat nicer since it can better distinguish between actual reallocs and initial allocs.

lib: Added buffer_get_writable_size()

lib: buffer - paranoid compile-time check for struct sizes At the moment, nothing guarantees that the public struct is big enough to contain the private struct. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: compile time checks for buffer creation Ensure the data buffer has as much space as the size parameter claims. This uses the strictest test GCC provides - the smallest containing object, and returning 0 for unknown size. Signed-off-by: Phil Carmody <phil@dovecot.fi>
